Pin Connections Overview On the output side, a pin is driven by writing to its corresponding bit in the DOUT register. Outputs can be configured as wired-OR, open drain, or push-pull with device-specific drive characteristics. WebAn open-drain or open-collector output pin is simply a transistor that is connected to the ground. Whenever we apply high input at the gate, drain, and source are shorted. Whenever we apply low input at the gate, drain, … '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… chiropractor or pt for sciatica
