SN54F38, SN74F38 QUADRUPLE 2ĆINPUT POSITIVEĆNAND BUFFERS WITH OPENĆCOLLECTOR OUTPUTS SDFS013A − MARCH 1987 − REVISED OCTOBER 1993 • Package Options Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs description These devices contain four independent 2-input NAND buffer gates with open-collector outputs. They perform the Boolean functions Y = A • B or Y = A + B in positive logic. SN54F38 . . . J PACKAGE SN74F38 . . . D OR N PACKAGE (TOP VIEW) 1A 1 1B 2 1Y 3 2A 4 2B 5 2Y 6 GND 7 14 VCC 13 4B 12 4A 11 4Y 10 3B 9 3A 8 3Y 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.
