The MC54/74HC244A is identical in pinout to the LS244. The device  
inputs are compatible with standard CMOS outputs; with pullup resistors,  
they are compatible with LSTTL 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.
