Pull-up Resistors Pull-up resistors are used to avoid self-biasing or floating digital inputs. The pull-up resistor connects the digital input to the correct biasing level and eliminates the uncertainty caused by a floating input. A floating input creates a no input condition and may cause random biasing leading to incorrect logic or decision. A logic […]
