Description

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 HighSpeed CMOS inputs. The HCT244A is an octal noninverting buffer line driver line receiver designed to be used with 3state memory address drivers, clock drivers, and other busoriented systems. The device has noninverted outputs and two activelow output enables.

The HCT244A is the noninverting version of the HCT240. See also HCT241.
