DUAL D-TYPE POSITIVE

EDGE-TRIGGERED

FLIP-FLOP

The MC74AC74/74ACT74 is a dual D-type flip-flop with Asynchronous Clear

and Set inputs and complementary (Q,Q) outputs. Information at the input is

transferred to the outputs on the positive edge of the clock pulse. Clock triggering

occurs at a voltage level of the clock pulse and is not directly related to the transition

time of the positive-going pulse. After the Clock Pulse input threshold voltage has

been passed, the Data input is locked out and information present will not be

transferred to the outputs until the next rising edge of the Clock Pulse input.

Asynchronous Inputs:

LOW input to S (Set) sets Q to HIGH level

LOW input to C (Clear) sets Q to LOW level

Clear and Set are independent of clock

Simultaneous LOW on C and S makes both Q and Q HIGH
