ISO3080,ISO3082,ISO3086,ISO3088 www.ti.com SLOS581I–MAY2008–REVISEDAPRIL2017 8 Detailed Description 8.1 Overview The ISO3080 and ISO3086 devices are isolated full-duplex differential line drivers and receivers while the ISO3082 and ISO3088 devices are isolated half-duplex differential line transceivers for TIA/EIA 485/422 applications. They are rated to provide galvanic isolation of up to 2500 V for 60 s as per the standard. They RMS have active-high driver enables and active-low receiver enables to control the data flow. They are available in twospeedgradessuitablefordatatransmissionupto200kbpsand20Mbps. When the driver enable pin, DE, is logic high, the differential outputs Y and Z follow the logic states at data input D. A logic high at D causes Y to turn high and Z to turn low. In this case the differential output voltage defined as V = V – V is positive. When D is low, the output states reverse, Z turns high, Y becomes low, and V is OD (Y) (Z) OD negative. When DE is low, both outputs turn high-impedance. In this condition the logic state at D is irrelevant. The DE pin has an internal pulldown resistor to ground, thus when left open the driver is disabled (high- impedance) by default. The D pin has an internal pullup resistor to V , thus, when left open while the driver is CC enabled,outputYturnshighandZturnslow. When the receiver enable pin, RE, is logic low, the receiver is enabled. When the differential input voltage defined as V = V – V is positive and higher than the positive input threshold, V , the receiver output, R, ID (A) (B) IT+ turns high. When V is negative and less than the negative and lower than the negative input threshold, V , ID IT– the receiver output, R, turns low. If V is between V and V the output is indeterminate. When RE is logic ID IT+ IT– high or left open, the receiver output is high-impedance and the magnitude and polarity of V are irrelevant. ID Internal biasing of the receiver inputs causes the output to go failsafe-high when the transceiver is disconnected fromthebus(open-circuit),thebuslinesareshorted(short-circuit),orthebusisnotactivelydriven(idlebus). 8.2 Functional Block Diagrams N O 14 R 3 ATI A 4 OL 13 RE S B 5 I DE C ANI 12Z 6 V D GAL 11Y Figure24.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information The ISO308x family consists of RS-485 transceivers commonly used for asynchronous data transmissions. Full- duplex implementation requires two signal pairs (four wires), and allows each node to transmit data on one pair while simultaneously receiving data on the other pair. For half-duplex transmission, only one pair is shared for both transmission and reception of data. To eliminate line reflections, each cable end is terminated with a termination resistor, R , whose value matches the characteristic impedance, Z0, of the cable. This method, (T) knownasparalleltermination,allowsforhigherdataratesoverlongercablelength. 9.2 Typical Application R R R R R R RE A RE A RE A DE B DE B DE B D D D D D D a) Independent driver and b) Combined enable signals for c) Receiver always on receiver enable signals use as directional control pin Copyright © 2016, Texas Instruments Incorporated Figure27.

ISO3080,ISO3082,ISO3086,ISO3088 www.ti.com SLOS581I–MAY2008–REVISEDAPRIL2017 Typical Application (continued) 9.2.1 DesignRequirements RS-485 is a robust electrical standard suitable for long-distance networking that can be used in a wide range of applications with varying requirements, such as distance, data rate, and number of nodes. Table 4 lists the designparameters. Table4.DesignParameters PARAMETER VALUE Pullupandpulldownresistors 1kΩto10kΩ Decouplingcapacitors 100nF 9.2.2 DetailedDesignProcedure The data rate and cable length have an inverse relationship which means the higher the data rate, the shorter thecablelength;andconversely,thelowerthedatarate,thelongerthecablelength.Whenconnectinganodeto the bus, the distance between the transceiver inputs and the cable trunk, known as the stub, should be as short as possible. Stubs present a nonterminated piece of bus line which can introduce reflections as the length of the stub increases. As a general guideline, the electrical length, or round-trip delay, of a stub should be less than one-tenth of the rise time of the driver. The RS-485 standard specifies that a compliant driver must be able to driver 32 unit loads (ULs), where 1 UL represents a load impedance of approximately 12 kΩ. Because the ISO308xfamilyconsistsof1/8ULtransceivers,connectingupto256receiverstothebusispossible. 9.2.3 ApplicationCurve Figure29.

The capacitors should be placed as close to CC1 CC2 the supply pins as possible. If only a single primary-side power supply is available in an application, isolated power can be generated for the secondary-side with the help of a transformer driver such as Texas Instruments' SN6501. For such applications, detailed power supply design and transformer selection recommendations are availableinSN6501TransformerDriverforIsolatedPowerSupplies. 11 Layout 11.1 Layout Guidelines ON-chip IEC-ESD protection is good for laboratory and portable equipment but never sufficient for EFT and surgetransientsoccurringinindustrialenvironments.Therefore,robustandreliablebusnodedesignrequiresthe use of external transient protection devices. Because ESD and EFT transients have a wide frequency bandwidth from approximately 3-MHz to 3-GHz, high-frequency layout techniques must be applied during PCB design. A minimumoffourlayersisrequiredtoaccomplishalowEMIPCBdesign(seeFigure30). • Layer stacking should be in the following order (top-to-bottom): high-speed signal layer, ground plane, power plane,andlow-frequencysignallayer. • Routing the high-speed traces on the top layer avoids the use of vias (and the introduction of their inductances) and allows for clean interconnects between the isolator and the transmitter and receiver circuits ofthedatalink. • Placing a solid ground plane next to the high-speed signal layer establishes controlled impedance for transmissionlineinterconnectsandprovidesanexcellentlow-inductancepathforthereturncurrentflow. • Placing the power plane next to the ground plane creates additional high-frequency bypass capacitance of approximately100pF/in2. • Routing the slower speed control signals on the bottom layer allows for greater flexibility as these signal links usuallyhavemargintotoleratediscontinuitiessuchasvias. • Place the protection circuitry close to the bus connector to prevent noise transients from penetrating your board. • Use V and ground planes to provide low-inductance. High-frequency currents might follow the path of least CC inductanceandnotnecessarilythepathofleastresistance. • Design the protection components into the direction of the signal path. Do not force the transient currents to divertfromthesignalpathtoreachtheprotectiondevice. • Apply 0.1-µF bypass capacitors as close as possible to the V -pins of transceiver, UART, and controller ICs CC ontheboard. • Use at least two vias for V and ground connections of bypass capacitors and protection devices to CC minimizeeffectivevia-inductance. • Use 1-kΩ to 10-kΩ pullup and pulldown resistors for enable lines to limit noise currents in these lines during transientevents. • Insert pulse-proof resistors into the A and B bus lines if the TVS clamping voltage is higher than the specified maximum voltage of the transceiver bus pins. These resistors limit the residual clamping current into the transceiverandpreventitfromlatchingup. • While pure TVS protection is sufficient for surge transients up to 1 kV, higher transients require metal-oxide varistors (MOVs) which reduce the transients to a few hundred volts of clamping voltage, and transient blockingunits(TBUs)thatlimittransientcurrenttolessthan1mA. 22 SubmitDocumentationFeedback Copyright©2008–2017,TexasInstrumentsIncorporated ProductFolderLinks:ISO3080 ISO3082 ISO3086 ISO3088

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
