The 74ABT74D is a high-speed 2-input low-power CMOS digital flip-flop manufactured by NXP Semiconductors. This dual D-type flip-flop has two independent D-type flip-flops each with complementary outputs for use in high-frequency digital applications. It has an asynchronous preset and clear for each flip-flop. This device has two D-type inputs, two data/clock inputs (D1, D2, CP1, CP2), two complementary outputs (Q1, Q2), two preset inputs (PR1, PR2), and two clear inputs (CL1, CL2). The output toggle action occurs on the CW/CW edges of both data/clock inputs. The device features the advantages of low power consumption, high noise immunity, and minimal output loading.
