WebPosted by London Rhodes on Apr 16, 2024 10:34:44 AM. An Open Collector output is an NPN transistor. An NPN transistor allows the sinking of current to common. It can be thought of as a switch that allows the circuit, after the load, to be connected to common. This means that a source is required for the output to work. Web19 de jul. de 2012 · For a PCI application, that requires an Open-Collector Digital Output I would recommend to go with the PCI-6518. ...

WebI am about to select a hall effect sensor. Two types are available: one has an open collector (OC) output, the other an RC output. The datasheet states that both are … '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…
