DESCRIPTION

The AC74 is an advanced high-speed CMOS

OCTAL D-TYPE FLIP FLOP WITH PRESET AND

CLEAR

NON

INVERTING

fabricated

with

sub-micron silicon gate and double-layer metal

wiring C

A signal on the D INPUT is transferred to the Q

OUTPUT during the positive going transition of

the clock pulse.

CLEAR and PRESET are independent of the

clock and accomplished by a low setting on the

appropriate input.

It is ideal for low power applications mantaining

high speed operation similar to equivalent Bipolar

Schottky TTL.

All

inputs and

outputs

are

equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
