The IN74HCT109A is identical in pinout to the LS/ALS109. The IN74HCT109A may be used as a level converter for interfacing TTL or NMOS outputs to High Speed CMOS inputs.
This device consists of two J-K flip-flops with individual set, reset, and clock inputs. Changes at the inputs are reflected at the outputs with the next low-to-high transition of the clock. Both Q to Q outputs are available from each flip-flop.
