KK74HC193A, Presettable 4-Bit Binary UP/DOWN Counter

TECHNICAL DATA KK74HC193A Presettable 4-Bit Binary UP/DOWN Counter High-Performance Silicon-Gate CMOS The KK74HC193A is identical in pinout to the LS/ALS193.

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-HIG
