DESCRIPTION
The 74ACT74 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
2
MOS tecnology.
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.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
