description

These devices contain three independent 3-input NAND gates with open-collector outputs. These gates perform the Boolean functionsor Y = A\+B\+C\ in positive logic. The open-collector outputs require pullup resistors to perform correctly. They 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 SN54ALS12A is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS12A is characterized for operation from 0°C to 70°C.
