DESCRIPTION  
The 74LCX244 is a low voltage CMOS OCTAL  
BUS BUFFER (NON-INVERTED) fabricated with  
sub-micron silicon gate and double-layer metal  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.
