SN74ABT574AN

Flip Flops Overview

The SN74ABT574AN is an octal edge-triggered D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It belongs to the ABT logic series and utilizes a PDIP-20 through-hole package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 6.6 ns, a high-level output current of -32 mA, and a low-level output current of 64 mA. It supports TTL input levels and functions at clock frequencies up to 200 MHz.

Flip Flops Feature Summary

• Provides eight independent D-type flip-flops with positive-edge triggering for parallel data storage.
• Features three-state outputs controlled by an output enable signal to facilitate bus-driven architectures.
• Utilizes BICMOS technology to achieve high-speed performance while maintaining compatibility with standard logic families.

Flip Flops Applications

• Parallel-to-serial or serial-to-parallel data conversion circuits
• Register files in microprocessor-based systems
• Bus interface buffering and isolation

Flip Flops Procurement Notes

Verify the specific suffix 'AN' confirms the PDIP-20 through-hole package variant. Ensure the order specifies the non-green Pb-free status if required, as environmental compliance details vary by production batch. Confirm RoHS status directly with the manufacturer or authorized distributor documentation prior to procurement.

Flip Flops Selection Notes

Select this component when a through-hole mounting solution is required for octal register applications. The ABT series offers superior speed compared to standard LS logic while maintaining pinout compatibility. Verify that the system power supply remains strictly within the 4.5 V to 5.5 V range to ensure reliable operation and prevent damage.

Flip Flops Part Context

This part is a member of the SN74ABT family, which combines the speed of Schottky TTL with CMOS low power consumption. It serves as a direct functional replacement for older octal registers like the 74LS374 but provides significantly faster switching speeds. The 'A' designation indicates optimized electrical characteristics within the series.

Flip Flops Replacement Considerations

SN74ABT574ADBR (SOIC-20), SN74ABT574APWR (TSSOP-20), SN74ABT574ARGYR (VQFN-20). These variants share identical logical functionality but differ in physical package dimensions and mounting style.
