The TC74HC74AF is a dual D-type flip-flop with set and reset belonging to the TC74HC series of high-speed CMOS logic devices manufactured by Toshiba Semiconductor and Storage. Each flip-flop has independent data (D), clock (CLK), set (SET), and reset (RST) inputs, and complementary outputs (Q and Q\'). The set and reset inputs are active low. The (EL) suffix indicates specific packaging and environmental compliance characteristics.
