DIGITAL ISOLATOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240097302 titled 'DIGITAL ISOLATOR

Simplified Explanation

The patent application describes a digital isolator with various circuits and elements to ensure accurate data transmission and isolation between different parts of a system.

• Edge detection circuit: Outputs first and second detection signals to detect edges in the input signals.
• Driving buffer circuit: Outputs first and second edge signals to drive the isolation element.
• Isolation element: Outputs first and second edge signals to isolate the input and output sides.
• Receiving inverter circuit: Outputs first and second reception signals based on the isolated signals.
• Latch circuit: Latches data based on the received signals and outputs to the output terminal.
• Switch circuit: Switches conduction states between reference potential and output signals.
• Control circuit: Controls the switching operation of the switch circuit.
