Quality Control: Learn More
STMicroelectronics 74AC74B is a dual D-type flip-flop featuring independent set and reset capabilities. This component, from the 74AC series, offers positive edge triggering and complementary outputs. With a typical clock frequency of 300 MHz and a maximum propagation delay of 10ns at 5V and 50pF load, it is well-suited for high-speed digital logic applications. The device operates over a wide voltage supply range of 2V to 6V and maintains a low quiescent current of 2 µA. It provides 24mA of drive capability for both high and low outputs. This through-hole mounted component, packaged in a 20-TSSOP, is commonly utilized in telecommunications, industrial automation, and consumer electronics.
