Part Description: Quadruple 2-Input Positive-AND Gates With Open-Collector Outputs

Part Details:

SN54ALS09, SN74ALS09 QUADRUPLE 2-INPUT POSITIVE-AND GATES WITH OPEN-COLLECTOR OUTPUTS SDAS084B ­ APRIL 1982 ­ REVISED DECEMBER 1994 · Package Options Include Plastic SN54ALS09 . . . J PACKAGE Small-Outline (D) Packages, Ceramic Chip SN74ALS09 . . . D OR N PACKAGE (TOP VIEW) Carriers (FK), and Standard Plastic (N) andCeramic (J) 300-mil DIPs 1A 1 14 VCC description 1B 2 13 4B 1Y 3 12 4A These devices contain four independent 2-input 2A 4 11 4Y positive-AND gates. They perform the Boolean 2B 5 10 3B functions Y = A · B or Y = A + B in positive logic. 2Y 6 9 3A The open-collector outputs require pullup GND 7 8 3Y resistors to perform correctly. These outputs maybe connected to other open-collector outputs to SN54ALS09 . . . FK PACKAGE implement active-low wired-OR or active-high (TOP VIEW) wired-AND functions. Open-collector devices areoften used to generate higher VOH levels. CC 1B 1A NC V 4B
