双JK正边沿触发触发器 Dual JK Positive Edge−Triggered Flip−Flop
The MC74AC109/ 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
