description  
These devices contain two independent 4-input  
positive-NAND gates. They perform the Boolean  
functions Y = A B C D or Y = A + B + C + D  
in positive logic.

The SN54ALS20A and SN54AS20 are  
characterized for operation over the full military  
temperature range of 55°C to 125°C. The  
SN74ALS20A and SN74AS20 are characterized  
for operation from 0°C to 70°C.
