... Presettable BCD/Decade UP/DOWN Counter High-Performance Silicon-Gate CMOS The IN74HC192 is identical in pinout to the LS/ALS192. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs. The counter has two separate clock inputs, a Count Up Clock and Count Down Clock inputs ...
