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.

• 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
