MC74HCT244A
Octal 3−State Noninverting
Buffer/Line Driver/
Line Receiver with
LSTTL−Compatible Inputs
High−Performance Silicon−Gate CMOS
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.
