Digital isolator HopeRF Micro-electronics CMT8261W1 featuring six channels and isolation voltage rating of 5.7kVrms
Product Overview
The CMT826X is a high-performance six-channel digital isolator utilizing SiO2 insulation technology, supporting isolation voltages up to 5.7kVrms. It facilitates communication between different power domains, preventing noise currents from affecting sensitive circuits. The device offers up to six forward or three backward channels, with configurable default output states (high for CMT826X1, low for CMT826X0). It boasts enhanced electromagnetic compatibility (EMC) with low power consumption and low radiation, meeting system-level ESD, EFT, surge, and radiation compliance requirements. Available in SOIC-16 wide and narrow body packages.
