TECHNICAL DATA
Presettable Counters
High-Speed Silicon-Gate CMOS
IN74AC163
The IN74AC163 is identical in pinout to the LS/ALS163,
HC/HCT163. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LS/ALS outputs.
The IN74AC163 is programmable 4-bit synchronous modulo-16
counter that feature parallel Load, synchronous Reset, a Carry Output for
cascading and count-enable controls.
The IN74AC163 is binary counter with synchronous Reset.
⢠Outputs Directly Interface to CMOS, NMOS, and TTL
⢠Operating Voltage Range: 2.0 to 6.0 V
⢠Low Input Current: 1.0 μA; 0.1 μA @ 25° C
⢠High Noise Immunity Characteristic of CMOS Devices
⢠Outputs Source/Sink 24 mA
