Product Description
Product Overview
The OSI140X series are high-reliability, four-channel digital isolators designed for robust communication in demanding environments. These chips offer high electromagnetic interference (EMI) immunity and low electromagnetic radiation, achieving data transfer rates up to 90 Mbps and common-mode transient immunity (CMTI) of 90 kV/s. With configurable enable and output default states, they minimize power consumption and support voltage level translation across different power domains. The OSI140X series boasts enhanced EMC performance for increased reliability and stability, and is undergoing certifications including UL1577, GB4943.1-2011, IEC60950-1, VDE V 0844-10, and AEC-Q100 (Grade 1).
