Dual JK Positive Edge-Triggered Flip-Flop
| | |  | | |
|
|
General Description
|
The AC/ACT109 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-Type flip-flop (refer to AC/ACT74 data sheet) by connecting the J and K# inputs together.
Asynchronous Inputs:
LOW input to S#D (Set) sets Q to HIGH level
LOW input to C#D (Clear) sets Q to LOW level
Clear and Set are independent of clock
Simultaneous LOW on C#D and S#D makes both Q and Q HIGH#
