Open drain and open collector
Web6 de mai. de 2024 · Open collector (drain) means there is nothing internal to the device connected to the collector of the output transistor, it's an OPEN circuit. The collector of a non conducting transistor has a high impedance (it's "floating"), so to hold it at a particular state (HIGH) a pullup resistor connects it to the Vcc of the circuit being switched. Web3 de nov. de 2024 · Open drain outputs require a pull-up resistor (R in the image above) for the output to be able to properly “output high”.The pull-up resistor is connected between the output pin and the output voltage (Vcc in the image above) that is desired for a high state.When the internal N-FET of the IC is off, R “pulls up” the output pin to Vcc and at …
