DESCRIPTION
The 74AC74 is an advanced high-speed CMOS
DUAL D-TYPE FLIP FLOP WITH PRESET AND
CLEAR fabricated with sub-micron silicon gate
and double-layer metal wiring C
A signal on the D INPUT is transferred to the Q
and Q OUTPUTS during the positive going

ORDER CODES
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.
