High−Performance Silicon−Gate CMOS

The MC74HCT244A is identical in pinout to the LS244. This

device may be used as a level converter for interfacing TTL or NMOS

outputs to High−Speed CMOS inputs. The HCT244A is an octal

noninverting buffer line driver line receiver 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.
