ON Semiconductor MC74AC74, MC74ACT74 Technical data

MC74AC74, MC74ACT74
Dual D−Type Positive Edge−Triggered Flip−Flop
The MC74AC74/74ACT74 is a dual D−type flipflop 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
