DESCRIPTION  
All inputs and outputs are equipped with  
protection circuits against static discharge, giving  
them 2KV ESD immunity and transient excess  
voltage.  
The 74AC244 is an advanced high-speed CMOS  
OCTAL BUS BUFFER (3-STATE) fabricated with  
sub-micron silicon gate and double-layer metal  
2
wiring C MOS tecnology.  
The G input controls four BUS BUFFERs.
