TECHNICAL DATA
IN74HCT244A
Octal 3-State Noninverting
Buffer/Line Driver/Line Receiver
High-Performance Silicon-Gate CMOS
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 driv-
ers, and other bus-oriented systems. The device has non-inverted outputs
and two active-low output enables.
