SN74ABT573ADWR

Latches Overview

The SN74ABT573ADWR is an octal D-type latch manufactured by Texas Instruments, belonging to the ABT logic series. It features a non-inverting true logic type with eight circuits housed in a SOIC-20 package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature from -40°C to +85°C. Key electrical parameters include a propagation delay of 5.7 ns, low-level output current of 32 mA, high-level output current of -32 mA, and maximum power supply current of 24 mA.

Latches Feature Summary

• Provides tri-state octal D-type latching functionality for data storage applications
• Features fast switching speeds characteristic of the ABT logic family
• Supports three-state outputs for effective bus-driven operations

Latches Applications

• Registering wide data words in digital systems
• Driving bus-oriented memory and interface circuits
• Performing parallel-to-serial conversion tasks

Latches Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-20 surface-mount package and reel packaging format. Confirm that the ABT series designation aligns with the required 4.5V to 5.5V operating voltage range for your system design. Ensure compatibility with standard industrial temperature specifications ranging from -40°C to +85°C before finalizing procurement orders.

Latches Selection Notes

Select this component when designing systems requiring high-speed data latching at standard 5V logic levels. The ABT series offers superior speed compared to legacy counterparts while maintaining robust drive capabilities. Consider the SOIC-20 footprint constraints and ensure the application benefits from the specific 5.7 ns propagation delay characteristics defined for this part number.

Latches Part Context

This component is part of the broader SN74ABT573A family of octal latches produced by Texas Instruments. It shares functional similarities with other devices in the ABT series but is distinguished by its specific package configuration and trailing suffix indicating reel-based distribution. It serves as a specialized solution for high-performance digital logic interfacing requirements.

Latches Replacement Considerations

Direct substitutes within the same family include SN74ABT573APWR, which utilizes a TSSOP-20 package instead of SOIC-20. Designers must verify pinout compatibility and physical footprint differences when considering alternative package options from the manufacturer's catalog.
