DESCRIPTION
The 74ACT374 is an advanced high-speed CMOS
OCTAL D-TYPE FLIP-FLOP with 3 STATE
OUTPUT NON INVERTING fabricated with
sub-micron silicon gate and double-layer metal
wiring C
These 8 bit D-Type Flip-Flop are controlled by a
clock input (CK) and an output enable input (OE).
On the positive transition of the clock, the Q
outputs will be set to the logic that were setup at
the D inputs.
While the (OE) input is low, the 8 outputs will be in

The output control does not affect the internal
operation of flip-flops; that is, the old data can be
retained or the new data can be entered even
while the outputs are off.
This device is designed to interface directly High
Speed CMOS systems with TTL and NMOS
components.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
