The 74HCT109PW is a positive-edge trigger Dual J K\ Flip-flop with set and reset. This high-speed Si-gate CMOS device is pin compatible with low power Schottky TTL LSTTL. It is specified in compliance with JEDEC standard no. 7A. The dual positive-edge triggered J K\ flip-flops with individual J, K\ inputs, clock CP inputs, set SD\\ and reset RD\\ inputs, also 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 J K\ design allows operation as a D-type flip-flop by tying the J and K\ inputs together. Schmitt-trigger action in the clock input makes the circuit highly tolerant to slower clock rise and fall times.
