STMicroelectronics 74HC series dual JK-type flip-flop, part number M74HC109B1R, features two independent 1-bit JK flip-flops with positive edge triggering. Each element includes preset and clear asynchronous inputs, with complementary outputs. This device operates from a 2V to 6V supply voltage range and offers a maximum clock frequency of 67 MHz. Typical propagation delay is 26ns at 6V with a 50pF load. Quiescent current is a low 2 µA, with output drive capabilities of 5.2mA for both high and low states. Input capacitance is rated at 5 pF. The M74HC109B1R is supplied in a 16-DIP (0.300", 7.62mm) through-hole package, suitable for operation across a wide temperature range of -55°C to 125°C (TA). Applications include digital logic systems, control circuits, and data buffering in industrial automation, consumer electronics, and telecommunications.
