KK74HCT163A
KK74HCT163A is Presettable Counters manufactured by Kodenshi AUK Group.
TECHNICAL DATA
Presettable Counters
High-Performance Silicon-Gate CMOS
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 patible 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
