Manufacturer: Texas Instruments

Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community ISO7520C, ISO7521C SLLSE39E – JUNE 2010 – REVISED MAY 2015 ISO752xC Low-Power 5 kVRMS Dual-Channel Digital Isolators.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The ISO7520C and ISO7521C provide galvanic isolation of up to 4243 VRMS for 1 minute per UL and 6000 VPK per VDE.

These devices are also certified to 5000 VRMS reinforced insulation per end equipment standards IEC 60950-1, IEC 61010-1, and IEC 60601-1.

These digital isolators have two isolated channels with unidirectional (ISO7520C) and bidirectional (ISO7521C) channel configurations.
