Pull-down Resistor
A resistor connected between a signal line and ground to ensure a defined low state when no other device drives the line.

Pull-down Resistor
A pull-down resistor is a Resistor connected between a signal line and Ground to ensure a defined low state.
Definition
Pull-down Resistors are used in digital circuits to ensure signal lines have a defined state when not actively driven. Less common than Pull-up Resistors but used in specific applications.
Key Points
- Connects signal to Ground
- Ensures low state when not driven
- Common values: 4.7kΩ to 10kΩ
- Prevents floating inputs
- Used in specific circuit configurations
