WebSinking Outputs,Open Collector. The open-collector transistor outputs can handle up to 50mA each. We highly recommend that you use an external power source as shown. It … '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… how is percentage calculated in icse class 10
