Description

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.
