TECHNICAL DATA
Octal 3-State Noninverting Buffer/Line
Driver/Line Receiver
High-Performance Silicon-Gate CMOS
KK74HCT241A
The KK74HCT241A is identical in pinout to the LS/ALS241. The
KK74HCT241A may be used as a level converter for interfacing TTL or
NMOS outputs to High Speed CMOS inputs.
This octal noninverting buffer/line driver/line receiver is designed to
be used with 3-state memory address drivers, clock drivers, and other
bus-oriented systems. The device has noninverting outputs and two
output enables. Enable A is active-low and Enable B is active-high.
• 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
