An open-drain output is an output which can only be driven low, not high; the output is either low or floating. Essentially the output is simply connected to the drain pin of a transistor (hence the term open-drain). When the Control line is driven high then the transistor short-...
On Fig. 2 we can see an open drain output. It is implemented using an N-channel MOS transistor that pulls the output pin to ground when the transistor is on and leaves it floating when the transistor is off. Fig. 2 Schematic of an open drain output Open drain outputs are most commonly...

An open-drain output buffer is operative to sustain relatively high voltages applied to an output pad. The open-drain buffer includes a number of floating wells, output switching devices and corresponding well-bias selectors to ensure that no gate oxide sustains voltages greater than a predefined ...

What is Open-drain? Definition An open-drain or open-collector output pin is driven by a single transistor, which pulls the pin to only one voltage (generally, to ground). When the output device is off, the pin is left floating (open, or hi-z). ...
Open-drain output configuration mode is either OFF (or GND) or in floating state. Let's now look at the structure of a GPIO pin port bit shown below. So how writing to an output works is that input a HIGH or LOW output state into the output data register and this goes into the Ou...
