These SN54ALS22B and SN74ALS22B devices contain two independent 4-input NAND gates. SN54ALS22B and SN74ALS22B perform the Boolean functions Y =A•B•C•D or Y = A+B+C+D 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 SN54ALS22B is characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ALS22B is characterized for operation from 0°C to 70°C.
