Overview
The MC74AC74DTR2G, produced by onsemi, is a dual D-type positive edge-triggered flip-flop. This component features asynchronous Clear and Set inputs along with complementary (Q, Q) outputs. The flip-flop transfers information from the input to the outputs on the positive edge of the clock pulse, making it suitable for various digital logic applications.
