SN74ACT574PWR

Flip Flops Overview

The SN74ACT574PWR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes a TSSOP-20 surface-mount package. Key electrical parameters include a propagation delay of 11 ns, with high-level output current capability of -24 mA and low-level output current of 24 mA. It supports TTL input levels and offers non-inverting polarity.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Three-state outputs allowing direct connection to bus systems
• Edge-triggered data storage synchronized with clock transitions
• Compatible with standard TTL input logic levels

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• General-purpose digital storage applications
• I/O buffering for microprocessor systems

Flip Flops Procurement Notes

Verify the specific suffix 'PWR' corresponds to the TSSOP-20 package and reel packaging format required for your assembly process. Confirm that the operating temperature range meets your environmental specifications. Ensure compatibility with your board's soldering profile for surface-mount technology. Cross-reference the manufacturer part number against official distributors to avoid counterfeit components.

Flip Flops Selection Notes

Select this component when an octal flip-flop with three-state outputs is required for bus-driven architectures. It is suitable for designs operating at 5V logic levels with TTL input compatibility. Consider the 11 ns propagation delay for timing constraints. Compare against other series like AHCT or ABT if lower power consumption or higher speed is needed instead.

Flip Flops Part Context

This part belongs to the SN74ACT574 family of octal D-type flip-flops. It is functionally similar to other variants such as SN74ACT574N or SN74ACT574DWR but differs in package type and manufacturing revision. The ACT series provides CMOS performance with TTL-compatible inputs, bridging older logic standards with modern CMOS technology.

Flip Flops Replacement Considerations

SN74ACT574DWRE4 and SN74ACT574DWRG4 are confirmed substitute part numbers offering equivalent functionality.
