54F/74F109
Dual JK Positive Edge-Triggered Flip-Flop
General Description
The ’F109 consists of two high-speed, completely indepen-
dent 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.
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
Features
n Guaranteed 4000V minimum ESD protection.
Ordering Code: See Section 0
