The IN74HC109A is identical in pinout to the LS/ALS109.The device inputs are compatible with standard CMOS tputs, with pullup resistors, they are compatible with LS/ALSTTL outputs.
This IN74HC109A 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.
