MC74HCT244A Datasheet | Motorola Semiconductor

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Octal 3-State Noninverting Buffer/Line Driver/ Line Receiver with LSTTL-patible Inputs High- Performance Silicon- Gate CMOS The MC54/74HCT244A 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. The HCT244A is the noninverting version of the HCT240.
