Open drain and open collector

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 ... Web7 de dez. de 2024 · What is an Open Drain? It is also called Open Collector which is a transistor having a connection with the ground pin. In a simple way, it behaves like a switch that gets connected or disconnected depending on the input signal.
