SN74LVC16245A www.ti.com SCES062Q–DECEMBER1995–REVISEDJUNE2014 9 Detailed Description 9.1 Overview The SN74LVC16245A device is designed for asynchronous communication between data buses. The control- functionimplementationminimizesexternaltimingrequirements. This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated. To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup CC resistor;theminimumvalueoftheresistorisdeterminedbythecurrent-sinkingcapabilityofthedriver. Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of this device as a translator in amixed3.3-V/5-Vsystemenvironment. This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs, off off preventingdamagingcurrentbackflowthroughthedevicewhenitispowereddown. 9.2 Functional Block Diagram 1 24 1DIR 2DIR 48 25 1OE 2OE 47 36 1A1 2A1 2 13 1B1 2B1 To Seven Other Channels To Seven Other Channels Pin numbers shown are for the DGG, DGV, and DL packages. 9.3 Feature Description • Wideoperatingvoltagerangefrom1.65Vto3.6V • Allowsdownvoltagetranslation • Inputsacceptvoltagesto5.5V • I featureallowsvoltagesontheinputsandoutputswhenV is0V off CC 9.4 Device Functional Modes Table3.FunctionTable INPUTS OPERATION OE DIR L L BdatatoAbus L H AdatatoBbus H X Isolation Copyright©1995–2014,TexasInstrumentsIncorporated SubmitDocumentationFeedback 11 ProductFolderLinks:SN74LVC16245A

This device can be used as two 8-bit transceivers or one 16-bit transceiver. It allows data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.

SN74LVC16245A www.ti.com SCES062Q–DECEMBER1995–REVISEDJUNE2014 Typical Application (continued) 10.2.1 DesignRequirements This device uses CMOS technology and has balanced output drive. Care should be taken to avoid bus contention because it can drive currents that would exceed maximum limits. The high drive will also create fast edgesintolightloads;therefore,routingandloadconditionsshouldbeconsideredtopreventringing. 10.2.2 DetailedDesignProcedure 1.

I vsFrequency CC 11 Power Supply Recommendations The power supply can be any voltage between the MIN and MAX supply voltage rating located in the RecommendedOperatingConditionstable. Each V pin should have a good bypass capacitor to prevent power disturbance. For devices with a single CC supply, 0.1 μF is recommended; if there are multiple V pins, then 0.01 μF or 0.022 μF is recommended for CC each power pin. It is acceptable to parallel multiple bypass caps to reject different frequencies of noise. A 0.1 μF and a 1 μF are commonly used in parallel. The bypass capacitor should be installed as close to the power pin as possibleforbestresults.

SN74LVC16245A SCES062Q–DECEMBER1995–REVISEDJUNE2014 www.ti.com 12 Layout 12.1 Layout Guidelines Whenusingmultiple-bitlogicdevices,inputsshouldneverfloat. In many cases, functions or parts of functions of digital logic devices are unused, for example, when only two inputs of a triple-input AND gate are used or only 3 of the 4 buffer gates are used. Such input pins should not be left unconnected because the undefined voltages at the outside connections result in undefined operational states. Figure 6 specifies the rules that must be observed under all circumstances. All unused inputs of digital logic devices must be connected to a high or low bias to prevent them from floating. The logic level that should be applied to any particular unused input depends on the function of the device. Generally they will be tied to GND or V , whichever makes more sense or is more convenient. It is generally acceptable to float outputs, CC unlessthepartisatransceiver.Ifthetransceiverhasanoutputenablepin,itwilldisabletheoutputsectionofthe partwhenasserted.ThiswillnotdisabletheinputsectionoftheIOs,sotheycannotfloatwhendisabled. 12.2 Layout Example V cc Input Unused Input Output Unused Input Output Input Figure6.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (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. Addendum-Page 1

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (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.
