MC74HCT244A集成电路（IC）的缓冲器驱动器接收器收发器规格书PDF中文资料

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.
