74VHCT574AMX

Overview

The Fairchild Semiconductor 74VHCT574AMX is an octal D-type flip-flop featuring three-state outputs, manufactured using advanced VHCT CMOS technology. It operates within a supply voltage range of 2.0V to 5.5V and supports data rates up to 100MHz. The device utilizes HCT-compatible logic levels, ensuring seamless integration with standard TTL systems while maintaining low power consumption characteristics typical of CMOS architectures.

Feature Summary

• Octal configuration providing eight independent D-type storage elements in a single package
• Three-state outputs allowing direct bus line interfacing without external buffers
• HCT-compatible input logic levels for backward compatibility with existing TTL designs

Applications

• High-speed data buffering on system buses
• Register file implementations in digital logic circuits
• Parallel-to-serial conversion stages

Procurement Notes

Verify the specific suffix 'AMX' against official datasheets to confirm package type and tape-and-reel specifications. Ensure the component matches the required operating temperature range and voltage thresholds for your target application before procurement.

Selection Notes

Select this component when requiring high-density octal storage with three-state control. It is suitable for applications needing HCT-level compatibility alongside low-voltage operation capabilities provided by the VHCT process technology.
