DESCRIPTION
The M54/74HC112 is a high speed CMOS DUAL J-K
FLIP-FLOP WITH PRESET AND CLEAR fabricated in
silicon gate C
speed performance of LSTTL combined with true
CMOS
M54HC112/M74HC112 dual JK flip-flop features indi-
vidual J,K, clock, and asynchronous set and clearinputs
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 withprotection circuits against static
discharge and transient excess voltage.
