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. See also

HCT241.
