74VHC175
Quad D-Type Flip-Flop
General Description
The VHC175 is an advanced high-speed CMOS device
fabricated with silicon gate CMOS technology. It achieves
the high-speed operation similar to equivalent Bipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation.
The VHC175 is a high-speed quad D-type flip-flop. The
device is useful for general flip-flop requirements where
clock and clear inputs are common. The information on the
D inputs is stored during the LOW-to-HIGH clock transition.
Both true and complemented outputs of each flip-flop are
provided. A Master Reset input resets all flip-flops, inde-
pendent of the Clock or D inputs, when LOW.
An input protection circuit insures 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 backup. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
