High-Speed Silicon-Gate CMOS
IN74ACT163
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 µA ; 0.1 mA @25°C
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, VIN and VOUT should be constrained to the range GND(VIN or
VOUT)VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.
