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 up to 90 kV/s. The OSI140X series features configurable enable and output default states for optimal power consumption and flexibility, and a wide input voltage range facilitates level shifting across different power domains. Enhanced EMC performance ensures reliability and stability. The devices are undergoing or have achieved certifications including UL1577, GB4943.1-2011, IEC60950-1, VDE V 0844-10, and AEC-Q100 (Grade 1).
