This datasheet also includes the 74LS112 variant, as both parts are published together in a single manufacturer document.
DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP
The SN54 / 74LS112A dual JK.
Key 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. SN54/74LS112A
