"Web31 de dez. de 2024 · Open Collector Outputs Summary. We have seen here in this tutorial about the open collector output that it can provide a current sink or current source output depending on the type of bipolar transistor, NPN-type or PNP-type, used. When an NPN-type transistor is in its “ON” state, it will provide or “sink” a path to ground. " - Opencollector.org
