These devices contain four independent 2-input  
positive-NOR buffers with open-collector outputs.  
Open-collector outputs require resistive pullup to

levels and commonly are used in wired-AND  
applications. These devices perform the Boolean  
functions Y = A B or Y = A + B in positive logic.

The SN54ALS33A is characterized for operation  
over the full military temperature range of 55°C  
to 125°C. The SN74ALS33A is characterized for  
operation from 0°C to 70°C.
