DESCRIPTION
The M74HC112 is an high speed CMOS DUAL
J-K FLIP-FLOP WITH PRESET AND CLEAR
fabricated with silicon gate C
2
MOS technology.
The M74HC112 dual JK flip-flop features
individual J, K, clock, and asynchronous set and
clear inputs for each flip-flop. When the clock goes
high, the inputs are enabled and data will be
accepted. The logic level of the J and K inputs
may be allowed to change when the clock pulse is
high and the bistable will function as shown in the
truth table. Input data is transferred to the input on
the negative going edge of the clock pulse.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
