Working Principles

SN74HC109N consists of two independent JK flip-flops, A and B. The flip-flops are positive-edge triggered, meaning they change state on the rising edge of the clock signal. The J and K inputs determine the output state based on the current state and the clock signal.

The clear input (CLR) asynchronously resets both flip-flops to a known state when activated. The buffered inputs and outputs ensure proper signal levels and improve noise immunity.
