This device contains six independent 2-input NOR  
drivers. It performs the Boolean functions  
Y = A + B or Y = A B in positive logic.  
The center-pin configuration reduces lead inductance when compared to the AS805B. This reduced lead  
inductance minimizes noise generated onto either the V  
high-current switching applications.  
or GND bus. This reduction is significant in  
CC  
The SN74AS1805 is characterized for operation from 0°C to 70°C.
