DM74ALS09 - Fairchild Semiconductor

DM74ALS09 Quad 2-Input AND Gate with Open Collector Outputs

This device contains four independent gates, each of which performs the logic AND function. The open-collector outputs require external pull-up resistors for proper logical operation. Pull-Up Resistor Equations Features s Switching specifications at 50 pF s Switching specifications guaranteed over full temperature and VCC range s Advanced oxide-isolated, io.
