FACT DATA
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 SD (Set) sets Q to HIGH level
LOW input to CD (Clear) sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on CD and SD makes both Q and Q HIGH
Outputs Source/Sink 24 mA
