Quad channel digital isolator HopeRF Micro-electronics CMT8040W1 in narrow and wide SOIC 16 packages
Product Overview
The CMT804X is a high-performance, quad-channel digital isolator utilizing silicon dioxide (SiO2) insulation. It supports isolation voltages up to 5 kVrms and is designed for communication between two different power domains, preventing noise currents from affecting sensitive circuits. The device features an enable pin for high-impedance output in multi-master configurations, reducing power consumption. It offers up to four forward and two backward channels. The CMT804X1 defaults to a high output level and the CMT804X0 defaults to a low output level upon loss of power or signal. With innovative chip design and layout, it achieves high electromagnetic compatibility (EMC) and low radiation, meeting system-level ESD, EFT, surge, and radiation compliance requirements. The CMT804X series is available in both narrow and wide SOIC-16 packages.
