SL74HC192 Datasheet (System Logic Semiconductor) - Presettable BCD/Decade UP/DOWN Counter

SL74HC192, Presettable BCD/Decade UP/DOWN Counter

SL74HC192 Presettable BCD/Decade UP/DOWN Counter High-Performance Silicon-Gate CMOS The SL74HC192 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.

The direction of counting is determined by which input is clocked.

The outputs change state synchronous with the LOW-to-HIGH transitions on the
