Logic-level conversion Ver mais Typically, open collector or open drain outputs connect to ground to represent low and disconnect to represent high. But by using a driving … Ver mais '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 Ver mais One problem such open-collector and similar devices with a pull-up resistor is the resistor consumes power constantly while the output is low. Higher operating speeds require lower resistor values for faster pull-up, which consume even more power. Also when driving a … Ver mais Pseudo open drain (POD) drivers have a strong pull-down strength but a weaker pull-up strength. The purpose is to reduce the overall power … Ver mais
