Flip Flops datasheet and documents for SN74ACT574NSR

SN74ACT574NSR

Flip Flops Overview

The SN74ACT574NSR is an octal edge-triggered D-type flip-flop with three-state outputs manufactured by Texas Instruments. It belongs to the 74ACT logic series and operates within a supply voltage range of 4.5 V to 5.5 V. The device features a propagation delay of 11 ns, with high-level output current of -24 mA and low-level output current of 24 mA. It is housed in a 20-SOIC surface-mount package and supports TTL input levels.

Flip Flops Feature Summary

Octal configuration providing eight independent D-type flip-flops
Three-state outputs for bus-oriented applications
Edge-triggered data storage on the positive clock transition
Non-inverting polarity for direct signal transmission

Flip Flops Applications

Parallel-to-serial data conversion circuits
Register files in microprocessor systems
Buffering and latching digital signals
Timing control logic in embedded systems

Flip Flops Procurement Notes

Verify the specific suffix NSR indicates tape-and-reel packaging when sourcing components. Confirm that the ACT logic family specifications align with system voltage requirements. Ensure compatibility with existing PCB footprints for the SOIC-20 package. Check for RoHS compliance status if environmental regulations apply to the final assembly process.

Flip Flops Selection Notes

Select this component for designs requiring moderate speed performance with standard CMOS drive capabilities. The ACT series offers improved switching speeds compared to legacy LS or ALS families while maintaining compatible pinouts. Consider the 11 ns propagation delay against system timing constraints. Evaluate the 20-SOIC package for automated surface-mount assembly efficiency.

Flip Flops Part Context

This part is part of the Texas Instruments 74ACT family, which bridges the performance gap between standard TTL and advanced CMOS technologies. The 74ACT574 variant specifically provides octal storage functionality. The NSR suffix denotes the reel-based packaging format suitable for high-volume manufacturing processes.
