TECHNICAL DATA
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Performance Silicon-Gate CMOS
IN74HCT244A
The IN74HCT244A is identical in pinout to the LS/ALS244. The de-
vice may be used as a level converter for interfacing TTL or NMOS out-
puts to High-Speed CMOS inputs.
The IN74HCT244A is an octal noninverting buffer/line driver/line re-
ceiver designed to be used with 3-state memory address drivers, clock
drivers, and other bus-oriented systems. The device has non-inverted
outputs and two active-low output enables.
• 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
