74ACTQ74PC集成电路（IC）的触发器规格书PDF中文资料

General Description

The 74ACTQ74 is a dual D-type flip-flop with Asynchronous Clear and Set inputs and complementary (Q, Q) out puts. 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.
