Product Description
BL714x Enhanced High-Speed Quad-Channel Digital Isolator
The BL714x series are high-performance quad-channel digital isolators designed to provide complete electrical isolation between input and output. Utilizing a dual-capacitive silicon dioxide (SiO2) insulation barrier, these isolators ensure robust isolation for digital signals. They offer a 100Mbps signal transmission rate, strong isolation capabilities including 100kV/s CMTI and 5kVRMS withstand voltage, and a wide operating temperature range of -40 to 125. The BL714x series is suitable for applications such as industrial automation, motor control, photovoltaic inverters, isolated power supplies, and medical equipment.
