1.3 Key Benefits of Functional Isolation

TI's functional isolators are key to such applications that require isolation for high voltage blocking and noise immunity, and not for to their certification compliance. These solutions are cost-effective replacements for applications that require isolation for ensuring proper system functionality, and not essentially system safety.

TI's functional isolators (ISO65xx) are available in industry standard packages, and additionally available in smaller, low-profile packages to enable high-channel density in compact system designs.

The following section covers various end equipments that can make use of functional digital isolators for conventional industry-wide applications.
