description

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 V_OH levels and commonly are used in wired-AND applications. These devices perform the Boolean functions Y = A\ • B\ or 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.
