The KK74AC244 is identical in pinout to the LS/ALS244, HC/HCT244. The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LS/ALS outputs. This octal noninverting buffer/line driver/line receiver is designed to be used with 3-state memory address drivers, clock drivers, and other bus-oriented systems. The device has noninverting outputs and two active-low output enables.
