If you are just starting out with electronics a term you may come across early on is “open drain”. It is very common in integrated circuits for output pins to be open drain. A datasheet for an IC will either state this for an output pin or show a functional circuit diagram with the output pin being internally connected to the otherwise “open drain” of an n-channel FET. Open drain outputs require a pull-up resistor (R in the image above) for the output to be able to properly “output high”. Th...
