Digital isolators

The terms galvanic, basic and reinforced are commonly used to describe isolation voltage ratings.

• Galvanic: Provides electrical insulation between circuits to address ground potential differences.
• Basic: A certified layer of protection against electrical shock. Ideal for systems with additional protective measures. Basic isolation delivers dependable performance while the insulation remains intact.
• Reinforced: A more robust certified insulation system that delivers the equivalent protection of two independent isolation elements, combining basic and supplementary protections. Rated for direct contact environments, eliminating the need for additional protective measures.

TI offers isolation devices in a wide variety of package options to save board space or meet maximum creepage for high voltage system requirements. From our most compact 2mm x 2mm QFN package to our largest 10.3mm x 14mm creepage DWW package, TI's packages deliver proven performance across every application.
