74HC109-Q100; 74HCT109-Q100 Dual JK flip-flop with set and reset; positive-edge-trigger Rev.
2 — 1 April 2020 Product data sheet 1.
General description The 74HC109-Q100; 74HCT109-Q100 is a dual positive edge triggered JK flip-flop featuring individual nJ and nK inputs.
It has clock (nCP) inputs, set (nSD) and reset (nRD) inputs and complementary nQ and nQ outputs.
The set and reset are asynchronous active LOW inputs and operate independently of the clock input.
The nJ and nK inputs control the state changes of the flip-flops as described in the mode select function table.
The nJ and nK inputs must be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operati...
