Presettable Counters High-Speed Silicon-Gate CMOS

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.
