SN74LVC16244A www.ti.com SCAS699C–AUGUST2003–REVISEDJUNE2014 9 Detailed Description 9.1 Overview This 16-bit buffer/driver is designed for 1.65-V to 3.6-V V operation. The SN74LVC16244A device is designed CC specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus- oriented receivers and transmitters. The device can be used as four 4-bit buffers, two 8-bit buffers, or one 16-bit buffer.Itprovidestrueoutputsandsymmetricalactive-lowoutput-enable(OE)inputs. 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. 9.2 Functional Block Diagram 1 25 1OE 3OE 47 2 36 13 1A1 1Y1 3A1 3Y1 46 3 35 14 1A2 1Y2 3A2 3Y2 44 5 33 16 1A3 1Y3 3A3 3Y3 43 6 32 17 1A4 1Y4 3A4 3Y4 48 24 2OE 4OE 41 8 30 19 2A1 2Y1 4A1 4Y1 40 9 29 20 2A2 2Y2 4A2 4Y2 38 11 27 22 2A3 2Y3 4A3 4Y3 37 12 26 23 2A4 2Y4 4A4 4Y4 Pin numbers shown are for the DGG, DGV, and DL packages. 9.3 Feature Description • Wideoperatingvoltagerange – Operatesfrom1.65Vto3.6V • Allowsdownvoltagetranslation – Inputsacceptvoltagesto5.5V • I feature off – AllowsvoltagesontheinputsandoutputswhenV is0V CC 9.4 Device Functional Modes Table3.FunctionTable (Each4-bitBuffer) INPUTS OUTPUT OE A Y L H H L L L H X Z Copyright©2003–2014,TexasInstrumentsIncorporated SubmitDocumentationFeedback 11 ProductFolderLinks:SN74LVC16244A

SN74LVC16244A SCAS699C–AUGUST2003–REVISEDJUNE2014 www.ti.com 10 Application and Implementation 10.1 Application Information The SN74LVC16244A device is a 16-bit buffer/driver. This device can be used as four 4-bit, two 8-bit, or one 16- bit buffer. It allows data transmission from the A bus to the Y bus with 4 separate enable pins that control 4 bits each. The output-enable (OE) input can be used to disable sections of the device so that the buses are effectively isolated. The device has 5.5 V tolerant inputs at any valid V which allows it to be used in multi- CC powersystemsandcanbeusedfordowntranslation. 10.2 Typical Application Regulated 3.6 V OE Vcc 1A1 1Y1 uC System Logic uC or 1A4 1Y4 LEDs System Logic GND Figure4. TypicalApplicationDiagram 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.

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 each CC 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. 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.ThiswillnotdisabletheinputsectionoftheI/Os,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. Addendum-Page 1

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