MC74VHC541  
Octal Bus Buffer  
The MC74VHC541 is an advanced high speed CMOS octal bus  
buffer fabricated with silicon gate CMOS technology. It achieves high  
speed operation similar to equivalent Bipolar Schottky TTL while  
maintaining CMOS low power dissipation.  
The MC74VHC541 is a noninverting type. When either OE1 or  
OE2 are high, the terminal outputs are in the high impedance state.  
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 7.0 V, allowing the interface of 5.0 V  
systems to 3.0 V systems.
