| Description | 2-Channel Bidirectional I2C Digital Isolator, 2.5kVrms, 1Mbps, SOIC-8 Package |
Product Overview
The ISO1540DR is a high-reliability, bidirectional digital isolator specifically designed for I2C communication interfaces. It provides galvanic isolation up to 2.5kVrms while supporting bidirectional data transfer without external direction control, making it ideal for isolated I2C, SMBus, and PMBus systems. The device features low power consumption, high noise immunity, wide operating voltage range, and integrated glitch filtering for stable communication in harsh industrial environments. With its compact SOIC-8 surface-mount package and industry-standard pinout, it enables easy integration into isolated sensor interfaces, industrial controls, and power management systems.
