DESCRIPTION

The ACT374 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

power

applications

mantaining

high

speed

operation similar to equivalent Bipolar Schottky

TTL.

These 8 bit D-Type flip-flops 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 logic state 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)

and while high level the outputs will be in a high

impedance state.

The output control does not affect the internal

operation of flip flop; that is, the old data can be

retained or the new data can be entered even

while the outputs are off.

The device is designed to interface directly High

Speed CMOS system 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.
