SN54ALS38B, sn74als38b quadruple 2-input positive-nand buffers with open-collector outputs sdas196b april 1982 revised december 1994 copyright ? 1994, texas instruments incorporated 1 post office box 655303 ? dallas, texas 75265 ? 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 with open-collector outputs. 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 often are used to generate higher v oh levels. the SN54ALS38B is characterized for operation over the full military temperature range of 55 c to 125 c. the sn74als38b is characterized for operation from 0 c to 70 c. function table (each gate) inputs output a b y h h l l xh x l h logic symbol 2 logic diagram (positive logic) 1 1a 2 1b 4 2a 5 2b 9 3a 10 3b 12 4a 13 4b 1y 3 2y 6 3y 8 4y 11 & 1 1a 2 1b 4 2a 5 2b 9 3a 10 3b 12 4a 13 4b 1y 3 2y 6 3y 8 4y 11 2 this symbol is in accordance with ansi/ieee std 91-1984 and iec publication 617-12. pin numbers shown are for the d, j, and n packages.
