1 / 4 page SN54ALS15A, SN74ALS15A TRIPLE 3INPUT POSITIVEAND GATES WITH OPENCOLLECTOR OUTPUTS SDAS016A − MARCH 1984 − REVISED MAY 1986 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77001 Copyright 1986, Texas Instruments Incorporated 5BASIC 1 • Package Options Include Plastic Small Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs • Dependable Texas Instruments Quality and Reliability description These devices contain three independent 3-input AND gates with open-collector outputs. These gates perform the Boolean functions Y = A •B•C or 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 SN54ALS15A is characterized for operation over the full military temperature range of − 55 °C to 125 °C. The SN74ALS15A is characterized for operation from 0 °C to 70°C.
