TECHNICAL DATA
IN74HCT163A
Presettable Counters
High-Performance Silicon-Gate CMOS
The IN74HCT163A is identical in pinout to the LS/ALS163. The
IN74HCT163 may be used as a level converter for interfacing TTL or
NMOS outputs to High Speed CMOS inputs.
The IN74HCT163A is programmable 4-bit synchronous counter that
feature parallel Load, synchronous Reset, a Carry Output for cascading
and count-enable controls.
The IN74HCT163A 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.
