Datasheet Summary
Octal D-Type Flip-Flop with 3-State Output
The MC74VHC574 is an advanced high speed CMOS octal flip- flip with 3- state output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.
This 8- bit D- type flip- flop is controlled by a clock input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state.
The internal circuit is posed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems to 3 V...
