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 composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems.
