SN74HCT573DWR

Latches Overview

The SN74HCT573DWR is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the 74HCT logic family. It features eight D-type latches with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 25 ns. It is designed for surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Latches Feature Summary

• Octal transparent D-type latch configuration with eight independent data paths
• Three-state output capability allowing direct bus-driven connections
• CMOS high-speed TTL-compatible logic family design

Latches Applications

• Registering fast-acting microprocessor data
• Portable applications requiring low power consumption
• Memory map registers and I/O addressing

Latches Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format on official distributor listings. Confirm the manufacturer is Texas Instruments to ensure compatibility with specified HCT logic levels. Check RoHS compliance status as indicated in current product documentation before finalizing procurement orders.

Latches Selection Notes

Select this component when interfacing between CMOS devices and TTL systems due to its HCT compatibility. Ensure the application requires an octal latch with three-state outputs for bus sharing. Verify that the 20-SOIC package fits the available PCB footprint and that the 4.5V to 5.5V supply voltage aligns with the system design.

Latches Part Context

This part belongs to the SN74HCT573 series of octal transparent latches. It shares functional similarities with other variants like the SN74ACT573 but differs in speed and voltage characteristics. The 'DWR' designation specifically indicates the SOIC-20 package type combined with reel packaging for automated assembly processes.

Latches Replacement Considerations

SN74HCT573DW is a tube-packaged equivalent from the same manufacturer. SN74HCT573DBR offers the same functionality in a SSOP-20 package.
