Overview
The MC74HC74ADTR2G is a Dual D Flip-Flop with Set and Reset, manufactured by onsemi. This device is part of the MC74HC74A series and is identical in pinout to the LS74. It features two D flip-flops, each with individual Set, Reset, and Clock inputs. The device inputs are compatible with standard CMOS outputs and, with pullup resistors, can also be compatible with LSTTL outputs. Information at the D-input is transferred to the corresponding Q output on the next positive-going edge of the clock input, and both Q and Q' outputs are available from each flip-flop. The Set and Reset inputs are asynchronous, providing flexible control over the flip-flop states.
