TECHNICAL DATA
IN74AC163
Presettable Counters
High-Speed Silicon-Gate CMOS
The IN74AC163 is identical in pinout to the LS/ALS163,
HC/HCT163. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS outputs.
The IN74AC163 is programmable 4-bit synchronous modulo-16
counter that feature parallel Load, synchronous Reset, a Carry Output for
cascading and count-enable controls.
The IN74AC163 is binary counter with synchronous Reset.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range GND≤(V
IN
or
V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
outputs must be left open.
