DESCRIPTION

The ACT574 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

MOS technology.

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.

PIN CONNECTION AND IEC LOGIC SYMBOLS

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.
