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, an...
The IN74HC10 is identical in pinout to the LS/ALS10. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
