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 demand compared to using both a strong pull-up and a strong pull-down. [ 10 ]
The high-impedance state of a given node in a circuit cannot be verified by a voltage measurement alone. A pull-up resistor (or pull-down resistor) can be used as a medium-impedance source to try to pull the wire to a high (or low) voltage level. If the node is not in a high-impedance state, extra current from the resistor will not ...
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 ...
The open collector input/output is a popular alternative to three-state logic. For example, the I²C bus protocol (a bi-directional communication bus protocol often used between devices) specifies the use of pull-up resistors on the two communication lines. When devices are inactive, they "release" the communication lines and tri-state their ...

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. 70.27.152.243 19:57, 20 July 2016 (UTC)
