74VHC574
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The VHC574 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 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 volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery back up. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
Features
