'Open drain output' is analogous to open collector operation, but uses a n-type MOS transistor (MOSFET) instead of an NPN. An open drain output connects to ground when a high voltage is applied to the MOSFET's gate, or presents a high impedance when a low voltage is applied to the gate. The voltage in this high impedance state would be floating (undefined) because the MOSFET is not conducting, which is why open drain outputs require a pull-up resistor connecte… WebFundamentals29 GPIO Output Configuration or Open Drain configuration or Push-Pull configurationFriends welcome to this video series on Embedded System. GPIO ... WebIf at least one of the outputs is in logic 0 state (active), the circuit sinks the current and brings the line to low voltage. You can use open-drain output if you are connecting multiple devices to a bus.
