TECHNICAL DATA
Presettable Counters
High-Performance Silicon-Gate CMOS
KK74HCT163A
The KK74HCT163A is identical in pinout to the LS/ALS163. The
KK74HCT163 may be used as a level converter for interfacing TTL or
NMOS outputs to High Speed CMOS inputs.
The KK74HCT163A is programmable 4-bit synchronous counter that
feature parallel Load, synchronous Reset, a Carry Output for cascading
and count-enable controls.
The KK74HCT163A 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
