Open drain and open collector
WebWhat 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).

Web6 de mai. de 2024 · Open collector (drain) means there is nothing internal to the device connected to the collector of the output transistor, it's an OPEN circuit. The collector of a non conducting transistor has a high impedance (it's "floating"), so to hold it at a particular state (HIGH) a pullup resistor connects it to the Vcc of the circuit being switched.

Web1.1.1 Open-Drain Pulling Low As described in the previous section, the Open-Drain setup may only pull a bus low, or "release" it and let a resistor pull it high. Figure 3 shows the flow of current to pull the bus low. The logic wanting to transmit a low will activate the pull-down FET, which will provide a short to ground, pulling the line low ...
