Overview
MC74AC109, MC74ACT109 Dual JK Positive Edge−Triggered Flip−Flop The MC74AC109/74ACT109 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 MC74AC74/74ACT74 data sheet) by connecting the J and K inputs together.
Asynchronous Inputs: LOW input to SD (Set) sets Q to HIGH level LOW input to CD (Clear) sets Q to LOW level Clear and Set are independent of clock Simultaneous LOW on CD and SD makes both Q and Q HIGH • Outputs Source/Sink 24 mA • ′ACT109 Has TTL Compatible Inputs VCC CD2 J2 K2 CP2 SD2 Q2 Q2 16 15 14 13 12 11 10 9 CD J K CP SD Q Q CD1 J1 K1 CP1 SD1 Q1 Q1 12345678 CD1 J1 K1 CP1 SD1 Q1 Q1 GND Figure 1.
