... 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 ...
