digital logic - Why are open-drain outputs needed?

WebIf at least one of the outputs is in logic 0 state (active), the circuit sinks the current and brings the line to low voltage. You can use open-drain output if you are connecting multiple devices to a bus. For example, you can use the open-drain output for system-level control signals that can be asserted by any device or as an interrupt. Web13 de abr. de 2024 · ‘Open Drain’ mode also known as ‘Open Collector’ is an output configuration which behaves like a switch that is either connected to ground or disconnected.

WebThe interrupt output can be configured to activate under two conditions (mutually exclusive): 1. When any input state differs from its corresponding input port register state. This is used to indicate to the system master that an input state has changed. 2. When an input state differs from a pre- configured register value (DEFVAL register). Web2 de jul. de 2024 · Open-drain output configuration is nothing but the top PMOS transistor is deactivated as shown in Figure1. When the transistor is ON, the pin pulled to the ground. When the transistor is OFF, the drain of the transistor will be floating or open. That’s the reason it is called an open drain.

'Open drain output' is analogous to open collector operation, but uses a n-type MOS transistor (MOSFET) instead of an NPN. An open drain output connects to ground when a high voltage is applied to the MOSFET's gate, or presents a high impedance when a low voltage is applied to the gate. The voltage in this high impedance state would be floating (undefined) because the MOSFET is not conducting, which is why open drain outputs require a pull-up resistor connecte…
