SN74HC573ADWR

Overview

The SN74HC573ADWR is an octal transparent D-type latch manufactured by Texas Instruments, featuring three-state outputs. It operates within a supply voltage range of 2 V to 6 V and supports surface-mount installation in a 20-SOIC package. The device exhibits a propagation delay of 23 ns, with output currents rated at 7.8 mA for both high and low states. It functions across a temperature range of -40°C to 85°C and complies with RoHS3 specifications.

Feature Summary

Octal transparent D-type latch architecture with eight independent data paths
Three-state outputs enabling direct bus line connections without external buffers
Non-inverting logic polarity for straightforward signal transmission

Applications

Parallel-to-serial data conversion circuits
Memory address latching in embedded systems
Driving LED arrays via microcontroller interfaces

Procurement Notes

Verify the specific suffix 'ADWR' corresponds to the SOIC-20 package and reel packaging configuration. Confirm that the operating temperature range meets the -40°C to +85°C requirement for your application environment. Ensure compatibility with the 2 V to 6 V supply voltage limits specified in the datasheet before integration.

Selection Notes

Select this component when an octal latch with three-state outputs is required for bus-oriented designs. The HC series offers standard CMOS performance suitable for general-purpose digital logic applications. Consider the 20-SOIC package dimensions for PCB layout constraints and verify that the 23 ns propagation delay aligns with system timing requirements.

Part Context

This part belongs to the SN74HC573A family of octal transparent D-type latches. It shares functional similarities with other devices in the 74HC series but is distinguished by its specific package type and manufacturing revision. The device serves as a fundamental building block for digital storage and interface buffering in consumer and industrial electronics.
