SN74AC574DW

Flip Flops Overview

The SN74AC574DW is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments, belonging to the 74AC logic series. It features eight independent D-type flip-flops with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 2V to 6V and supports a maximum clock frequency of 153 MHz at 5V. Propagation delay is specified as 6ns under standard conditions. It includes TTL-compatible inputs and offers high output drive capability with 24mA source and sink currents.

Flip Flops Feature Summary

• Octal configuration providing eight independent D-type edge-triggered flip-flops for parallel data storage
• Three-state outputs allowing direct connection to bus systems without external buffers
• TTL-compatible input structures ensuring compatibility with various logic families
• High-speed performance supporting clock frequencies up to 153 MHz

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register implementations
• Clock domain crossing synchronization stages
• General-purpose digital data latching applications

Flip Flops Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the component matches the exact SN74AC574DW designation rather than similar variants like SN74AC574DWR or SN74ACT574DW. Check RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides valid traceability documents for quality assurance purposes.

Flip Flops Selection Notes

Select this component when designing systems requiring octal data storage with high-speed operation and three-state bus interfacing capabilities. The AC series offers faster switching speeds compared to standard 74LS counterparts while maintaining broader voltage tolerance. Consider the 20-SOIC package constraints for PCB layout and thermal management. Evaluate power consumption requirements as the AC series draws higher static current than LV or LVC alternatives.

Flip Flops Part Context

This component belongs to the SN74AC574 family of octal D-type flip-flops produced by Texas Instruments. It is part of the broader 74AC logic line designed for high-speed digital applications. The DW suffix indicates a 20-pin Small Outline Integrated Circuit (SOIC) package variant. This series serves as a fundamental building block for sequential logic circuits in industrial and consumer electronics.
