74F109 | DUAL J-K POSITIVE-EDGE-TRIGGERED FLIP-FLOP |
The F109 consists of two high-speed, pletely independent transition clocked JK flip-flops. The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D-type flip-flop (refer to F74 data sheet) by connecting the J and K inputs.
