It handles data rates up to 25Mbps. ## What the key ratings mean for your BOM The 3750Vrms isolation voltage is the primary safety spec. The 25Mbps data rate is adequate for most sensor and control links. ## Temperature grade and deployment environment Rated for -40°C to 125°C, this part fits industrial automation cabinets, outdoor telecom enclosures, and under-hood automotive modules. The capacitive coupling technology has no LED wear-out mechanism, so it holds up over temperature cycling better than optocoupler-based isolators. The 8-SOIC package is a standard footprint — no special layout beyond the usual 8mm creepage clearance for 3750Vrms.","metaTitle":"MAX12931BASA+ Digital Isolator, 2-Ch, 25Mbps, 3750Vrms","metaDescription":"MAX12931BASA+ 2-channel digital isolator, 25Mbps data rate, 3750Vrms isolation, capacitive coupling, -40°C to 125°C, SOIC-8.
