SN54/74LS114A DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP
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.

* 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.
