DESCRIPTION

The 74ACT74 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.

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.
