What is "wired-OR" (or open-collector/open-drain) logic, and what is one common use?
Correct! Well done.
Incorrect.
The correct answer is A) A configuration where multiple gate outputs can be connected directly to a single line (with a pull-up resistor), such that the line goes low if any connected output drives it low — commonly used for shared interrupt or bus lines like I2C
Correct Answer
A configuration where multiple gate outputs can be connected directly to a single line (with a pull-up resistor), such that the line goes low if any connected output drives it low — commonly used for shared interrupt or bus lines like I2C
Open-collector/open-drain outputs allow multiple devices to share a single bus line safely — any device can pull the line low, and a pull-up resistor returns it high when no device is actively driving it low — commonly used in protocols like I2C for shared signal/interrupt lines.
