MC74VHC244  
Octal Bus Buffer  
The MC74VHC244 is an advanced high speed CMOS octal bus  
buffer fabricated with silicon gate CMOS technology.  
The MC74VHC244 is a noninverting 3--state buffer, and has two  
active--low output enables. This device is designed to be used with  
3--state memory address drivers, etc.  
The internal circuit is composed of three stages, including a buffer  
output which provides high noise immunity and stable output. The  
inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems  
to 3 V systems.
