Web15 de fev. de 2024 · In open-drain, current has to be drawn through the pullup resistor continuously to maintain the output low state. The pullup resistor can be increased to reduce current, but not without limit. At some point, it still needs to source enough current to charge line capacitance quickly enough, and to drive any loads on the line. Web12 de jan. de 2011 · open drain push pull The push-pull output actually uses two transistors. Each will be on to drive the output to the appropriate level: the top transistor will be on when the output has to be driven high and the bottom transistor will turn on when the output has to go low. The open-drain output lacks the top transistor.
