SEMICONDUCTOR TECHNICAL DATA  
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 7V, allowing the interface of 5V systems to 3V systems.
