FAST AND LS TTL DATA
DUAL JK POSITIVE
EDGE-TRIGGERED FLIP-FLOP
The MC54/74F109 consists of two high-speed, completely 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
flip-flop (refer to F74 data sheet) by connecting the J and K
inputs together.

Asynchronous Inputs:
LOW Input to SD sets Q to HIGH level
LOW Input to CD sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on CD and SD makes both Q and Q HIGH
