Product Description

Product Overview

The CMT8100/CMT8101 series are high-reliability, bidirectional I2C isolators compliant with AEC-Q100 and UL1577 safety standards. They offer robust electrical isolation (3.75 kVrms, 5 kVrms), high electromagnetic compatibility (EMC) with low emissions, and low power consumption. Supporting I2C clock speeds up to 2 MHz and wide supply voltage ranges (2.5 V to 5.5 V), these devices facilitate level translation and enhance system reliability and stability.
