74HCT109D
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 plementary Q and Q outputs. The set and reset are asynchronous active LOW inputs and operate independently of the clock input.
