SN54/74LS107A DUAL JK NEGATIVE EDGE-TRIGGERED FLIP-FLOP The SN54 / 74LS107A is a Dual JK Flip-Flop with individual J, K, Direct Clear and Clock Pulse inputs. Output changes are initiated by the HIGH-to-LOW transition of the clock. A LOW signal on CD input overrides the other inputs and makes the Q output LOW. The SN54 / 74LS107A is the same as the SN54 / 74LS73A but has corner power pins.
