The SN54/ 74LS114A offers common clock and common clear inputs and
individual J, K, and set inputs. These monolithic dual flip-flops are designed
so that 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 times are observed. Input data is transferred
to the outputs on the negative-going edge of the clock pulse.
