HopeRF Micro electronics CMT8040N0 digital isolator high speed quad channel with multi master enable pin
CMT804X High-Speed Quad-Channel Digital Isolator
The CMT804X is a high-performance, quad-channel digital isolator utilizing silicon dioxide (SiO2) isolation technology, supporting up to 5 kVrms isolation voltage. It facilitates communication between two different power domains, preventing noise currents from entering local grounds or disrupting sensitive circuits. The device features an enable pin for high-impedance output in multi-master applications, reducing power consumption. The CMT804X offers up to four forward and two backward channels. Depending on the model (CMT804X1 defaults to high, CMT804X0 defaults to low output upon power or signal loss), it provides high electromagnetic immunity and low radiation with innovative chip design and layout. Available in SOIC-16 wide and narrow body packages.
