SN54F38, SN74F38 QUADRUPLE 2-INPUT POSITIVE-NAND BUFFERS WITH OPEN-COLLECTOR OUTPUTS SDFS013A – MARCH 1987 – REVISED OCTOBER 1993 • SN54F38 . . . J PACKAGE SN74F38 . . . D OR N PACKAGE (TOP VIEW) Package Options Include Plastic Small-Outline Packages, Ceramic Chip Carriers, and Standard Plastic and Ceramic 300-mil DIPs 1A 1B 1Y 2A 2B 2Y GND 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. 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.
