SN74LV574ADWR

Flip Flops Overview

The SN74LV574ADWR is an octal edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 5.5 V and features a maximum propagation delay of 7.1 ns at 5 V. The device utilizes a TSSOP-20 surface-mount package and includes active-low clear functionality. It supports clock frequencies up to 175 MHz and maintains typical output ground bounce below 0.8 V at 3.3 V.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• 3-state outputs allowing direct connection to bus lines without external buffers
• Wide operating voltage range supporting both 2 V and 5.5 V systems

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register storage
• High-speed buffering applications requiring low ground bounce

Flip Flops Procurement Notes

Verify the specific suffix 'PW' or 'DR' against the datasheet to confirm the exact package type, as 'SN74LV574A' covers multiple form factors. Ensure the design accounts for the 2 V minimum supply requirement if using lower voltage logic levels. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

Flip Flops Selection Notes

Select this component when an octal latch with high-speed performance and wide voltage compatibility is required. It is suitable for designs needing direct bus interfacing due to its 3-state output capability. Consider the 7.1 ns propagation delay for timing-critical paths and ensure the thermal characteristics of the TSSOP-20 package meet the application's power dissipation needs.

Flip Flops Part Context

This part belongs to the SN74LV574A family of octal edge-triggered D-type flip-flops. It is designed for high-speed digital applications requiring reliable data storage and transfer. The LV series offers improved performance over standard logic families while maintaining compatibility with various voltage domains.

Flip Flops Replacement Considerations

Direct substitutes include other octal D-type flip-flops with 3-state outputs from compatible logic families. Verify pinout compatibility and electrical specifications such as propagation delay and output current drive before swapping components.
