Description

The 74AC74PC 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 of the 74AC74PC:

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

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

Clear and Set are independent of clock

Simultaneous LOW on C_D and S_D makes both Q and Q HIGH
