Overview
The MC74ACT74DR2G is a dual D-type positive edge-triggered flip-flop produced by onsemi. This component is part of the 74ACT series, known for its high-speed and low-power CMOS logic. The device features asynchronous Clear and Set inputs, along with complementary (Q, Q) outputs. Information at the input is transferred to the outputs on the positive edge of the clock pulse, making it suitable for a variety of digital circuit applications.
