74AC74, 74ACT74 Dual D-Type Positive Edge-Triggered Flip-Flop
Features
■ ICC reduced by 50% ■ Output source/sink 24mA ■ ACT74 has TTL-compatible inputs
General Description
The AC/ACT74 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 positivegoing pulse.
After the Clock Pulse input threshold
voltage has been passed, the Data input is locked out and i...
