Input data is transferred to the input on The M74HC112 dual JK flip-flop features the negative going edge of the clock pulse. individual J, K, clock, and asynchronous set and All inputs are equipped with protection circuits clear inputs for each flip-flop. When the clock goes against static discharge and transient excess high, the inputs are enabled and data will be voltage. accepted. The logic level of the J and K inputs PIN CONNECTION AND IEC LOGIC SYMBOLS July 2001 1/12 M74HC112 INPUT AND OUTPUT EQUIVALENT CIRCUIT
