CC When the latch-enable (LE) input is high, the Q outputs follow the data (D) inputs. When LE is low, the Q outputs arelatchedatthelogiclevelsoftheDinputs. A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high or low) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive the bus lines significantly. The high-impedance state and increased drive provide the capability to drive bus lines without interfaceorpull-upcomponents. OE does not affect the internal operations of the latches. Old data can be retained or new data can be entered whiletheoutputsareinthehigh-impedancestate. To ensure the high-impedance state during power up or power down, OE should be tied to V through a pull-up CC resistor;theminimumvalueoftheresistorisdeterminedbythecurrent-sinkingcapabilityofthedriver. 9.2 Functional Block Diagram OE LE C1 1Q 1D 1D To Seven Other Channels 9.3 Feature Description • Wideoperatingvoltagerange – Operatesfrom2Vto5.5V • Allowsdownvoltagetranslation – Inputsacceptvoltagesto5.5V • Slowedgesreduceoutputringing 9.4 Device Functional Modes Table1.FunctionTable (EachLatch) INPUTS OUTPUT OE LE D Q L H H H L H L L L L X Q 0 H X X Z Copyright©1995–2014,TexasInstrumentsIncorporated SubmitDocumentationFeedback 11 ProductFolderLinks:SN54AHC573 SN74AHC573

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 10.1 Application Information TheSN74AHC573isalow-driveCMOSdevicethatcanbeusedforamultitudeofbus-interfacetypeapplications where output ringing is a concern. The low drive and slow edge rates will minimize overshoot and undershoot on the outputs. The inputs accept voltages up to 5.5 V allowing down translation to the V level.

Care should be taken to avoid bus contention because it can drive currents that would exceed maximum limits.

Each V pin should have a good bypass capacitor to prevent power disturbance. For devices with a single CC supply, 0.1 μF bypass capacitor is recommended. If there are multiple V pins, 0.01 μF or 0.022 μF is CC recommended for each power pin. It is acceptable to parallel multiple bypass capacitors to reject different frequencies of noise. A 0.1 μF and 1 μF are commonly used in parallel. The bypass capacitor should be installed asclosetothepowerpinaspossibleforbestresults. 12 Layout 12.1 Layout Guidelines Whenusingmultiplebitlogicdevicesinputsshouldnoteverfloat. 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. Specified in Figure 6 are 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 CC outputs unless the part is a transceiver. If the transceiver has an output enable pin, it will disable the outputs section of the part when asserted. This will not disable the input section of the IO’s so they cannot float when disabled. 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. (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.
