TECHNICAL DATA
K K
74ACT161
Presettable Counter
High-Speed Silicon-Gate CMOS
The
KK
74ACT161 is identical in pinout to the LS/ALS161,
HC/HCT161. The
KK
74ACT161 may be used as a level converter for
interfacing TTL or NMOS outputs to High Speed CMOS Inputs.
The
KK
74ACT161 is programmable 4-bit synchronous modulo-16
counter that feature parallel Load, asynchronous Reset, a Carry Output for
cascading and count-enable controls.
The
KK
74ACT161 is binary counter with asynchronous 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
