DESCRIPTION
The M54/74HC11 2 is a high speed CMOS DUAL J-K
FLIP-F LOP WITH PRESET AN DCLEARfabricated i n
silicon gate C2MOStechnology. It has the same high
speed performance of LSTTL combined with true
CMOS low power consumption. The
M54HC112/M74HC112 dual JK flip-flop features individual J,K,clock,andasynchronous setandclearinputs
for each flip-flop. When the clock goes high, the inputs
areenabled and data willbeaccepted. The logiclevel
of the J and K inputs may be allowed to change when
theclock pulseis high andthebistable will function as
shown in the truth table. Inpu t data is transferred to the
input on the negative going edge of the clock pulse. All
inputsareequippe d withprotectioncircuits ag ainststatic
discharge and transient excess voltage.
