These devices contain four independent 2-input positive-NAND buffers. They perform the Boolean functions or Y = A\ + B\ in positive logic. The open-collector outputs require pullup resistors to perform correctly. These outputs may be connected to other open-collector outputs to implement active-low wired-OR or active-high wired-AND functions. Open-collector devices are often used to generate high VOH levels.
The SN54ALS03B is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS03B is characterized for operation from 0°C to 70°C.
