SL74HCT163D Overview

Presettable Counters(High-Performance Silicon-Gate CMOS)

SL74HCT163
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 SL74HCT163 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
