General description
The 74HC109; 74HCT109 is a dual positive edge triggered JK flip-flop featuring individual J and K inputs, clock (CP) inputs, set (SD) and reset (RD) inputs and complementary Q and Q outputs.
The set and reset are asynchronous active LOW inputs and operate independently of the clock input.
The J and K inputs control the state changes of the flip-flops as described in the mode select function table.
The J and K inputs must be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operation.
The JK design allows operation as...
