Pinout

Pin Name Type Function
1 1J input Synchronous J input of flip-flop 1, which must be stable one set-up time before the HIGH-to-LOW clock transition for predictable operation.
2 ~{1Q} output Complement output of flip-flop 1, the inverse of 1Q.
3 1Q output True output of flip-flop 1.
4 1K input Synchronous K input of flip-flop 1, which must be stable one set-up time before the HIGH-to-LOW clock transition for predictable operation.
5 2Q output True output of flip-flop 2.
6 ~{2Q} output Complement output of flip-flop 2, the inverse of 2Q.
7 GND power_in Ground (0 V) reference for all voltages.
8 2J input Synchronous J input of flip-flop 2, which must be stable one set-up time before the HIGH-to-LOW clock transition for predictable operation.
9 2CP input Clock input of flip-flop 2, triggered on the HIGH-to-LOW edge.
10 2R input Asynchronous reset input of flip-flop 2, active LOW and independent of the clock.
11 2K input Synchronous K input of flip-flop 2, which must be stable one set-up time before the HIGH-to-LOW clock transition for predictable operation.
12 1CP input Clock input of flip-flop 1, triggered on the HIGH-to-LOW edge.
13 1R input Asynchronous reset input of flip-flop 1, active LOW and independent of the clock.
14 VCC power_in Supply voltage; recommended range is 2.0 V to 6.0 V for 74HC107 and 4.5 V to 5.5 V for 74HCT107.
