SN74LVC574APW

Flip Flops Overview

The SN74LVC574APW is an octal D-type flip-flop featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 1.65 V to 3.6 V and utilizes a TSSOP-20 surface-mount package. The device exhibits a maximum propagation delay of 7.8 ns and supports clock frequencies up to 150 MHz. It provides high drive capability with output currents of ±24 mA. The component functions as a non-inverting logic element suitable for buffering and register applications in low-voltage systems.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops within a single integrated circuit
• Three-state outputs designed to facilitate direct connection to bus-oriented systems
• CMOS-compatible inputs ensuring compatibility with TTL logic levels across the operating voltage range

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• I/O port buffering and interface management
• Working registers for temporary data storage
• Bus driver implementations requiring tri-state control

Flip Flops Procurement Notes

Verify that the ordering suffix matches 'PW' to confirm the TSSOP-20 package variant. Ensure the specific sub-grade designation aligns with project requirements. Confirm RoHS compliance status through official documentation. Validate pinout configurations against schematic designs prior to integration. Check for any recent product change notifications affecting specifications.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with tri-state bus interfacing capabilities. The LVC series offers superior speed compared to standard HC logic while maintaining low power consumption. Consider the 1.65 V minimum supply voltage for compatibility with modern low-voltage microcontrollers. Evaluate thermal performance and PCB layout constraints associated with the TSSOP-20 package dimensions.

Flip Flops Part Context

This part belongs to the SN74LVC574A family of octal edge-triggered D-type flip-flops. It shares functional similarities with variants like the SN74LVC574ADBR but differs in physical packaging. The LVC series is engineered for high-speed operation in low-voltage environments, distinguishing it from higher-voltage counterparts like the SN74HCT574.

Flip Flops Replacement Considerations

The SN74LVC574ADBR serves as a functional substitute offering identical electrical characteristics within an SSOP-20 package. Designers must verify footprint compatibility when transitioning between TSSOP and SSOP form factors. Other family members may provide alternative mounting options without altering logical functionality.
