These devices contain four independent 2-input positive-NOR buffers with open-collector outputs. Open-collector outputs require resistive pullup to perform correctly. They can deliver higher VOH 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 to 125. The SN74ALS33A is characterized for operation from 0to 70.

† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
