General Description

The VHCT574A is an advanced high speed CMOS octal flip-flop with 3-STATE output fabricated with silicon gate CMOS technology. It achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintain ing the CMOS low power dissipation. This 8-bit D-type flip flop is controlled by a clock input (CP) and an Output Enable input (OE). When the OE input is HIGH, the eight outputs are in a high impedance state.
