Presettable Counters High-Performance Silicon-Gate CMOS

The SL74HC163 is identical in pinout to the LS/ALS163. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALSTTL outputs.
The SL74HC163 is programmable 4-bit synchronous counter that feature parallel Load, synchronous Reset, a Carry Output for cascading and count-enable controls.

The SL74HC163 is binary counter with synchronous Reset.
• Outputs Directly Interface to CMOS, NMOS, and TTL
• Operating Voltage Range: 2.0 to 6.0 V
• Low Input Current: 1.0 mA
• High Noise Immunity Characteristic of CMOS Devices
