SLS SL74HCT163D, SL74HCT163N Datasheet

Semiconductor

Presettable Counters

High-Performance Silicon-Gate CMOS

The SL74HCT163 is identical in pinout to the LS/ALS163. The
SL74HCT163 may be used as a level converter for interfacing TTL or
NMOS outputs to High Speed CMOS inputs.

The SL74HCT163 is programmable 4-bit synchronous counter that
feature parallel Load, synchronous Reset, a Carry Output for cascading
and count-enable controls.

The SL74HCT1 63 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

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 V
