Pull-up and pull-down resistors are often used when interfacing a switch or some other input with a microcontroller or other digital gates. Most microcontrollers have built-in programmable pull-up and/or pull-down resistors, so fewer external components are needed. It is possible to interface a...
Pull up is to clamp an uncertain signal to a high level with a resistor, and the resistor also acts as a current limiter. In the same way, pull down m...
Pull up and pull down resistors Pull-up resistor:1, when the TTL driving circuit of COMS circuit, if the high level is lower than the minimum high level COMS circuit output TTL circuit (usually 3.5V), then you need to pull in the resistance of the output end of the TTL, in order ...
Pull-down resistors(less common) : outputs to provide a known output impedance. I2C protocol bus Calculate actual values of pull up and pull-down resistor In order to calculate pull-up and pull-down resistance, we need to first apply the formula in Ohm’s Law: Resistance = Voltage/Current...
Pull up and pull down resistors are truly brilliant when working with chips (ICs), because with them, we can define the pins of chips. Pull up or pull down resistors are normally connected to the pins of chips so that they can define the state of the pins. ...
If you used two 60-Ohm resistors in series instead, then the power rating required would be about half as much. External pull-up and pull-down resistances are optional on RS-485 buses and are sometimes used so that there is a defined differential level even if no transmitters...
I use TXS0102 for the tx rx pins of the BG95M3 GPS&GSM integrated circuit. In the datasheet of TXS0102, it tells me to pull down the OE pin, but in the datasheet of BG95M3, it says that I need to add pull down and pull up resistors. Should I add an extra pu...

The terms pull-up and pull-down imply how the resistor is wired (will be presented in the next part).For a digital input pin, we should NOT use both pull-up resistor and pull-down resistor. Use one of them only. The pull-up or pull-down resistors are used ONLY with digital input ...
