74AHC573PW,112

Latches Overview

The 74AHC573PW,112 is an octal D-type transparent latch with 3-state outputs manufactured by Nexperia. It operates within a supply voltage range of 2.0 V to 5.5 V and features balanced propagation delays. The device includes latch enable (LE) and output enable (OE) inputs, with Schmitt-trigger action on all inputs for high noise immunity. It is housed in a TSSOP20 package (SOT360-1) and supports operating temperatures from -40 °C to +125 °C.

Latches Feature Summary

• Octal D-type transparent latch architecture with 3-state outputs
• Wide supply voltage operation from 2.0 V to 5.5 V
• Overvoltage tolerant inputs allowing use as translators in mixed voltage environments
• High noise immunity due to Schmitt-trigger action on all inputs

Latches Applications

• Bus-oriented applications requiring data storage and transfer
• Mixed voltage translation between different logic families
• General-purpose digital logic circuits requiring latching functionality

Latches Procurement Notes

Verify the specific ordering suffix matches the required package type and temperature range. Confirm that the component meets RoHS compliance standards for your region. Ensure the supplier provides valid traceability documentation. Check for any recent product change notices regarding assembly or marking updates before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with 3-state outputs is required for bus systems. It is suitable for designs needing wide voltage flexibility and robust noise immunity. Consider the TSSOP20 package constraints for PCB layout. Verify input voltage levels match the source logic family specifications.

Latches Part Context

This part belongs to the 74AHC series of high-speed CMOS logic devices. It is functionally identical to the 74AHC373 variant but utilizes D-type transparent latch behavior rather than edge-triggered flip-flop logic. The PW suffix indicates the TSSOP20 plastic thin shrink small outline package.

Latches Replacement Considerations

The 74AHCT573PW,112 serves as a TTL-compatible alternative within the same family. Other pin-compatible options include the 74AHC373 for similar latch functions. Verify electrical characteristics and input thresholds when substituting with non-Nexperia equivalents.
