ST isolated digital interfaces transfer high-speed digital signals across a galvanic isolation barrier to help protect sensitive circuitry from high voltages, ground loops and transient surges in industrial environments. Built on ST thick-oxide isolation technology, for demanding applications, they deliver high-fidelity signal transmission at data rates up to 100 Mbps, making them well-suited for control applications, where signal timing directly affects system performance. They operate from 3 V to 5.5 V, support 3.3 V / 5 V level translation, and provide a compact, reliable and longer-lasting alternative to conventional optocouplers.

Product type
Benefits
- High-speed data transfer
Supports up to 100 Mbps, enabling fast and reliable communication across the isolation barrier. - Strong noise immunity
High common-mode transient immunity and Schmitt trigger inputs help maintain signal integrity in noisy industrial environments. - Compact replacement for optocouplers
A smaller, more reliable alternative to conventional optical isolation with longer lifetime and lower maintenance. - Flexible supply and logic translation
Operates from 3 V to 5.5 V and supports 3.3 V / 5 V level translation for easy integration into mixed-voltage systems. - Safety and isolation robustness
Thick-oxide galvanic isolation provides strong creepage and clearance with certified isolation ratings for demanding industrial designs.
