74VHCT574A Octal D-Type Flip-Flop with 3-STATE Outputs
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 maintaining the CMOS low power dissipation.
This 8-bit D-type flipflop 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.
Protection circuits ensure that 0V to 7V can be applied to the input and output (Note 1) pins without regard to...
