SN54/74LS113A

DUAL JK NEGATIVE

EDGE-TRIGGERED FLIP-FLOP

The SN54/74LS113A offers individual J, K, set, and clock 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 setup

times are observed. Input data is transferred to the outputs on the

negative-going edge of the clock pulse.
