DESCRIPTION

The 74AC74 is an advanced high-speed CMOS

DUAL D-TYPE FLIP FLOP WITH PRESET AND

CLEAR

fabricated with sub-micron silicon gate

A signal on the D INPUT is transferred to the Q

and Q OUTPUTS 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.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
