Overview
The 74AC74MTCX is a dual D-type flip-flop integrated circuit produced by Fairchild Semiconductor. This component is part of the 74AC 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.
