High-Speed Silicon-Gate CMOS
The IN74ACT163A is identical in pinout to the LS/ALS163
HC/HCT163. The IN74ACT163 may be used as a level converter
for interfacing TTL or NMOS outputs to High Speed Cmos
Inputs.
The IN74ACT163A is programmable 4-bit synchronous
counter that feature parallel Load, synchronous Reset, a Carry
Output for cascading and count-enable controls.
The IN74ACT163A is binary counter with synchronous Reset.
TTL/NMOS Compatible Input Levels
Outputs Directly Interface to CMOS, NMOS, and TTL
Operating Voltage Range: 4.5 to 5.5 V
Low Input Current: 1.0 A ; 0.1 mA @25C
Ouptuts Source/Sink 24mA

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

or V

)

.
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.
