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 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

PIN CONNECTION AND IEC LOGIC SYMBOLS

ORDER CODES

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.
