Presettable 4-Bit Binary UP/DOWN Counter
High-Performance Silicon-Gate CMOS

The SL74HC193 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.

 • Outputs Directly Interface to CMOS, NMOS, and TTL
 • Operating Voltage Range: 2.0 to 6.0 V
 • Low Input Current: 1.0 μA
 • High Noise Immunity Characteristic of CMOS Devices
