  2. Pull-up resistor - Wikipedia

    en.wikipedia.org/wiki/Pull-up_resistor

    A resistor with relatively high resistance is called a "weak" pull-up or pull-down; when the circuit is open, it will pull the output high or low more slowly, but will draw less current. This current, which is essentially wasted energy, only flows when the switch is closed, and technically for a brief period after it is opened until the charge ...

  3. Open collector - Wikipedia

    en.wikipedia.org/wiki/Open_collector

    The output is usually connected to an external pull-up resistor, which pulls the output voltage to the resistor's supply voltage when the transistor is off. For PNP open collector outputs, the emitter of the PNP transistor is internally connected to the positive voltage rail , so the collector outputs a high voltage when the transistor is on or ...

    For example, a 10 ohm resistor connected in parallel with a 5 ohm resistor and a 15 ohm resistor produces ⁠ 1 / 1/10 + 1/5 + 1/15 ⁠ ohms of resistance, or ⁠ 30 / 11 ⁠ = 2.727 ohms. A resistor network that is a combination of parallel and series connections can be broken up into smaller parts that are either one or the other.

    en.wikipedia.org/wiki/Depletion-load_NMOS_logic

    A resistor (with the current simply proportional to the voltage) would be better, and a current source (with the current fixed, independent of voltage) better yet. A depletion-mode device with gate tied to the opposite supply rail is a much better load than an enhancement-mode device, acting somewhere between a resistor and a current source.

  6. 1-Wire - Wikipedia

    en.wikipedia.org/wiki/1-Wire

    A 1-Wire network is a single open drain wire with a single pull-up resistor. The pull-up resistor pulls the wire up to 3 or 5 volts. The master device and all the slaves each have a single open-drain connection to drive the wire, and a way to sense the state of the wire.

  9. Talk:Pull-up resistor - Wikipedia

    en.wikipedia.org/wiki/Talk:Pull-up_resistor

    The voltage drop across any resistor depends on the current flowing; in a circuit, currents can change and consequently the voltages at specific points in that circuit may go up at one end of what is called a pull-up resistor, or down at one end of what is called a pull-down resistor.
