74F109N – PHILIPS

The 74F109N, manufactured by Philips, is a high-speed, advanced Schottky clamped JK positive-edge-triggered flip-flop fabricated in a bipolar process. This dual flip-flop features individual J, K, clock, and set-direct inputs for each flip-flop, enabling versatile sequential logic implementation. The device incorporates AND-gated J and K inputs to provide input logic flexibility. Propagation delay times are typically in the nanosecond range, characteristic of the F series logic family, making it suitable for high-frequency applications. The N suffix indicates a plastic dual-in-line (DIP) package, facilitating through-hole mounting on printed circuit boards. The 74F109N operates from a standard 5V supply and provides complementary Q and /Q outputs, enhancing its utility in various digital systems requiring bistable storage elements with asynchronous set capability.
