SN74LV574APWT

Flip Flops Overview

The SN74LV574APWT is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the LV logic series and utilizes a 20-TSSOP surface-mount package. The device operates within a supply voltage range of 2 V to 5.5 V, supporting standard CMOS input types. Key electrical specifications include a propagation delay of 19.6 ns, with high-level output current of -16 mA and low-level output current of 16 mA. It functions at clock frequencies up to 175 MHz and maintains static current consumption of 20 µA.

Flip Flops Feature Summary

• Provides eight independent D-type flip-flops with positive-edge triggering for data storage applications.
• Features three-state outputs that allow direct connection to bus lines without external drivers.
• Supports wide operating voltage ranges from 2 V to 5.5 V for flexible system integration.

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffering and register operations in digital systems
• Bus-oriented memory interface designs

Flip Flops Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and specific tape-and-reel packaging requirements during procurement. Ensure compatibility with existing PCB footprints and thermal management strategies before finalizing orders.

Flip Flops Selection Notes

Select this component when designing systems requiring low-voltage operation with moderate speed capabilities. Consider the 20-TSSOP package constraints for space-limited layouts. Evaluate the 19.6 ns propagation delay against system timing requirements to ensure signal integrity across the eight-bit data path.

Flip Flops Part Context

This part is part of the SN74LV574A family, which includes variants like SN74LV574APWR and SN74LV574APW. These components share identical logical functionality but differ in packaging or manufacturing revisions. The APWT suffix specifically denotes the TSSOP-20 package configuration.

Flip Flops Replacement Considerations

Public documentation indicates the SN74LV574APWT is discontinued. Potential substitutes include SN74LV574APWR or SN74LV574APW, provided they match the required TSSOP-20 footprint and electrical characteristics.
