Open collector open drain差異

WebDefinition. An open-drain or open-collector output pin is driven by a single transistor, which pulls the pin to only one voltage (generally, to ground). When the output device is off, the … '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 … Ver mais Open collector output and open drain output utilize a transistor as a switch that either disconnects or connects an integrated circuit (IC) output pin to ground, instead of outputting a specific voltage or current Ver mais An open collector output processes an IC's output through the base of an internal NPN transistor, whose collector is an external output pin. The emitter of the NPN transistor is … Ver mais Note: since the name of this article is "open collector", this section primarily uses the term "open collector", however "open drain" generally … 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 output is indicated on schematics with these IEEE symbols: ⎐ - open collector or similar (e.g. open drain) pin that outputs a low voltage when on or hi-Z when off. ⎒ - variant with internal pull-up resistor to provide a high voltage when off. ⎏ - … 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. … 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
