TECHNICAL DATA
Presettable Counters
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
