MC74VHC374
Octal D-Type Flip-Flop
with 3-State Output
The MC74VHC374 is an advanced high speed CMOS octal
flip−flip with 3−state output fabricated with silicon gate CMOS
technology. It achieves high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining CMOS low power
dissipation.
This 8−bit D−type flip−flop is controlled by a clock input and an
output enable input. When the output enable input is high, the eight
outputs are in a high impedance state.
The internal circuit is composed of three stages, including a buffer
output which provides high noise immunity and stable output. The
inputs tolerate voltages up to 7V, allowing the interface of 5V systems
to 3V systems.

This device contains protection
circuitry to guard against damage
due to high static voltages or electric
fields. However, precautions must
be taken to avoid applications of any
voltage higher than maximum rated
voltages to this high−impedance cir-
cuit. For proper operation, V
in
and
V
out
should be constrained to the
range GND v (V
in
or V
out
) v V
CC
.
Unused inputs must always be
tied to an appropriate logic voltage
level (e.g., either GND or V
CC
).
Unused outputs must be left open.
