SN54ALS09

Package Options Include Plastic Small-Outline (D) Packages, Ceramic Chip Carriers (FK), and Standard Plastic (N) and Ceramic (J) 300-mil DIPs description 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 SN54ALS09 is characterized for operation over the full military temperature range of – 55°C to 125°C. The SN74ALS09 is characterized for operation from 0°C to 70°C.
