These devices contain four independent 2-input positive-AND gates. They perform the Boolean functions Y = A • B 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 higher VOH levels. The SN74ALS09N is characterized for operation from 0°C to 70°C.
