74ABT574CMSA

Flip Flops Overview

The Fairchild Semiconductor 74ABT574CMSA is an octal D-type flip-flop featuring buffered positive edge-triggered clock inputs and three-state outputs. It operates within a supply voltage range of 4.5V to 5.5V, with a maximum propagation delay of 5ns at 5V with 50pF load. The device provides high drive capability, offering 32mA source current and 64mA sink current. It is housed in a 20-lead SSOP package (MTC20) suitable for surface mount applications.

Flip Flops Feature Summary

• Octal D-type flip-flop architecture with separate data inputs per stage
• Three-state outputs designed for efficient bus-oriented system interconnections
• Buffered clock input ensures clean signal triggering across all stages
• High-current output drivers support direct interface to heavy loads

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory register interfaces
• High-speed data latch modules
• Clock distribution buffering systems

Flip Flops Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix CMSA corresponds to the SSOP-20 package variant. Check for obsolescence status as legacy ABT series components may have limited availability. Ensure environmental compliance documentation matches project requirements prior to final procurement decisions.

Flip Flops Selection Notes

Select this component when designing systems requiring octal storage with high drive strength. Compare against LVTH series if lower voltage operation is needed. Verify that the 5.5V maximum rating aligns with the target system power rails. Consider pin-compatible alternatives from other manufacturers if supply chain constraints exist for the original Fairchild part number.

Flip Flops Part Context

This component belongs to the 74ABT logic family, known for advanced BJT-CMOS technology offering high speed and low power consumption. It serves as a standard octal register solution in digital logic design. The CMSA suffix specifically denotes the small outline package configuration used in compact surface-mount assemblies.

Flip Flops Replacement Considerations

Public confirmed substitute part numbers include SN74ABT574ADBR and SN74ABT574APWR from Texas Instruments. These equivalents maintain functional compatibility within the same logic family specifications.
