Overview
The MC74AC74DR2G is a dual D-type positive edge-triggered flip-flop produced by onsemi. This component is part of the MC74AC74 and MC74ACT74 series, which are designed for high-speed logic applications. The device features asynchronous Clear and Set inputs, along with complementary (Q, Q) outputs. The information at the input is transferred to the outputs on the positive edge of the clock pulse, making it suitable for various digital circuit designs.
