DUAL JK NEGATIVE
EDGE-TRIGGERED FLIP-FLOP
The SN54/74LS112A dual JK flip-flop features individual J, K, clock, and
asynchronous set and clear inputs to 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 perform according to the truth table as long as minimum set-up
and hold time are observed. Input data is transferred to the outputs on the
negative-going edge of the clock pulse.

* Both outputs will be HIGH while both SD and CD are LOW, but the output states
are unpredictable if SD and CD go HIGH simultaneously.
H, h = HIGH Voltage Level
L, I = LOW Voltage Level
X = Don’t Care
l, h (q) = Lower case letters indicate the state of the referenced input (or output)
l, h (q) =
one set-up time prior to the HIGH to LOW clock transition.
