SN74ABT574APW

Flip Flops Overview

The SN74ABT574APW is an octal edge-triggered D-type flip-flop from Texas Instruments' ABT logic series. It features eight non-inverting D inputs and three-state outputs housed in a 20-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V, with a typical propagation delay of 6.6 ns. It supports TTL input levels and provides high drive capability with output currents of -32 mA (high) and 64 mA (low).

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package.
• Three-state outputs enable direct connection to bus systems without external buffers.
• ABT technology ensures fast switching speeds with low power consumption.
• Compatible with standard TTL input voltage levels for broad interface support.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register file storage elements in microprocessor systems
• Bus interface buffering and latching applications
• Digital signal processing data path registers

Flip Flops Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-20 package variant rather than other packaging options like 'PWR' or 'ADBR'. Confirm RoHS compliance status through official manufacturer documentation, as environmental declarations may vary by production batch. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target design.

Flip Flops Selection Notes

Select this component when an octal register with high-speed performance and strong drive capability is required. The ABT series offers superior speed compared to standard 74HC devices while maintaining compatibility with 5V logic systems. Consider the TSSOP-20 package for surface-mount assembly constraints. Evaluate thermal dissipation requirements given the high output current capabilities during active switching operations.

Flip Flops Part Context

This device belongs to the SN74ABT574A family of octal flip-flops. It shares functional similarities with variants such as SN74ABT574APWR and SN74ABT574ADBR, differing primarily in packaging type and reel specifications. The ABT series represents a high-performance BiCMOS logic family designed for demanding digital applications requiring fast propagation delays.

Flip Flops Replacement Considerations

SN74ABT574APWRG4 serves as a direct equivalent with identical electrical characteristics but utilizes a tape-and-reel packaging format instead of tube packaging. Other compatible alternatives include SN74ABT574ADBR and SN74ABT574ARGYR, which offer the same logical function across different physical packages such as SOIC and QFN.
