Quality Control: Learn More
STMicroelectronics M74HCT74B1R is a dual, 1-bit, positive-edge triggered D-type flip-flop from the 74HCT series. Each element features asynchronous preset and clear inputs, along with complementary outputs. This through-hole component is housed in a 14-DIP package with a 0.300" (7.62mm) lead pitch. Operating from a 4.5V to 5.5V supply, it offers a maximum clock frequency of 48 MHz and a typical propagation delay of 33ns at 4.5V with a 50pF load. Quiescent current is a low 2 µA, with output current capabilities of 4mA high and 4mA low. Input capacitance is rated at 5 pF. The M74HCT74B1R is suitable for applications in industrial controls, consumer electronics, and telecommunications. It operates across a temperature range of -55°C to 125°C.
