SN74AC574PW

Flip Flops Overview

The SN74AC574PW is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2V to 6V. The device utilizes a 20-pin SOIC package for surface-mount installation. Key electrical parameters include a propagation delay of 6ns at 5V with 50pF load, a maximum clock frequency of 153MHz, and output drive currents of ±24mA. It functions as a single circuit with non-inverting polarity.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops on a single chip
• Three-state outputs allowing direct bus-driven connections without external buffers
• Wide operating voltage range supporting both 2V and 5V logic systems

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Register storage in microprocessor-based systems
• Buffering and latching operations in communication interfaces

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the Mouser or DigiKey part numbers with the TI datasheet to validate availability and exact physical dimensions before finalizing procurement orders.

Flip Flops Selection Notes

Select this component when designing systems requiring high-speed data latching with wide voltage compatibility. The AC series offers faster switching speeds compared to standard HC variants. Consider the 20-SOIC footprint for PCB layout constraints. Evaluate the ±24mA output current capability against load requirements to ensure signal integrity across the bus structure.

Flip Flops Part Context

This device belongs to the SN74AC574 family of octal flip-flops. It serves as a high-performance alternative to older logic families, offering improved speed and lower power consumption. The PW suffix indicates a plastic small-outline package suitable for automated surface-mount assembly processes commonly used in modern electronics manufacturing.

Flip Flops Replacement Considerations

SN74AC574DWR is a verified equivalent part number from Texas Instruments featuring the same logical function but utilizing a different SOIC package variant.
