5-177FAST AND LS TTL DATA

DUAL JK NEGATIVEEDGE-TRIGGERED FLIP-FLOP

The SN54/74LS107A is a Dual JK Flip-Flop with individual J, K, DirectClear and Clock Pulse inputs. Output changes are initiated by theHIGH-to-LOW transition of the clock. A LOW signal on CD input overrides theother inputs and makes the Q output LOW.

The SN54/74LS107A is the same as the SN54/74LS73A but has cornerpower pins.

NOTE:The Flatpak version has thesame pinouts (ConnectionDiagram) as the Dual In-LinePackage.
