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