MC74AC74, MC74ACT74
Dual D−Type Positive
Edge−Triggered Flip−Flop
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.
