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.
