DESCRIPTION
The 74AC374 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 C2MOS technology.
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
a normal logic state (high or low logic level); while
OE is in high level, the outputs will be in a high
impedance state.
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.
All
inputs
and
outputs
are
equipped
with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
