The CD74HC109E is a JK-type flip-flop integrated circuit manufactured by Texas Instruments. This component contains two flip-flop elements, each capable of holding a single bit of data. Packaged in a 16-pin dual in-line package (DIP) with a 0.300-inch (7.62mm) width, it operates efficiently with positive edge triggering. The device features set (preset) and reset capabilities and possesses a typical input capacitance of 10 pF. It achieves a propagation delay of approximately 31 nanoseconds when operating at 6V with a 50 pF load, making it suitable for various digital logic operations that require edge-sensitive data storage.
