Description

   The 74HC/HCT109 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A.

   The 74HC/HCT109 are dual positive-edge triggered, JK flip-flops with individual J, K inputs, clock (CP) inputs, set(S D) and reset (R D) inputs; also complementary Q and Q outputs.

   The set and reset of the 74HC/HCT109 are asynchronous active LOW inputs and operate independently of the clock input.

   The J and K inputs of the 74HC/HCT109 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 predictableoperation.

   The JK design of the 74HC/HCT109 allows operation as a D-type flip-flop by tying the J and K inputs together.

   Schmitt-trigger action of the 74HC/HCT109 in the clock input makes the circuit highly tolerant to slower clock rise and fall times.
