1 / 13 page SN54ALS03B, SN74ALS03B QUADRUPLE 2INPUT POSITIVENAND BUFFERS WITH OPENCOLLECTOR OUTPUTS SDAS013B − MARCH 1984 − REVISED DECEMBER 1994 Copyright 1994, Texas Instruments Incorporated 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 POST OFFICE BOX 1443 • HOUSTON, TEXAS 77251−1443 • 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-NAND buffers. 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 high VOH levels. The SN54ALS03B is characterized for operation over the full military temperature range of − 55 °C to 125 °C. The SN74ALS03B is characterized for operation from 0 °C to 70°C.
