74VHC574 Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The VHC574 is an advanced high speed CMOS octal flipflop with 3-STATE output fabricated with silicon gate CMOS technology.
It achieves the high speed operation similar to equivalent Bipolar
Schottky TTL while maintaining 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.
An input protection circuit ensures that 0V to 7V can be applied to the input pins without regard to the supply volta...
