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...
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...
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...
上拉电阻与下拉电阻（Pull-up resistor and pull-down 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, ...
Pull-down resistors work in the same manner as pull-up resistors, except that they pull the pin to a logical low value. They are connected between ground and the appropriate pin on a device. An example of a pull-down resistor in a digital circuit can be seen in the following figure. ...
Pull up resistors pull up a pin to a HIGH state. Pull down resistors pull down a pin to a LOW state. Therefore, we have well-defined pins. When pins are well defined, we have control over the circuit. When pins are floating and are not defined, we have no control because the pins...
The most basic function of pull-up or pull-down resistors (collectively referred to as "pull resistors") is to clamp a signal line with an uncertain state to a high level (pull-up) or a low level (pull-down) through a resistor. Regardless of its specific usage, this basic function is...
Pull up resistor vs pull down; The Differences To better illustrate the differences between pull-up and pull-down resistors, I’ll be providing a side-to-side comparison through a table below: As observed, there aren’t much differences between both type resistors as they share vastly similar...

Pull Up/Down resistors are very important for optimized logic operation. For example, TTL Logic: Logic low is defined as 0.8 volts or less, but not negative. Logic High is 2.0 volts to 5 volts Voltages higher than 0.8 and lower than 2.0 are "Undefined" or Illegal. TT...
