DCOM CMP485H
The CMP485S is a complete galvanically isolated half-duplex RS485 transceiver designed for bi-directional data communication or multipoint bus transmission at rates up to 2Mbits per second. The both sides of the interface can be powered through the integrated, isolated, low noise, low power dc/dc converter. The internal digital isolators and an isolation power transformer provide 2500Vrms of isolation between the line transceiver and the logic interface.| Part No. | CMP485H |

DESCRIPTION
No external components are needed. Only a single 5.0V power supply is required on the input side. This device is ideal for systems where the ground loop is broken allowing for large common mode voltage variation. Uninterrupted communication is guaranteed for common mode transients greater than 30kV/μs. Maximum data rates are 2Mbps. Their BiCMOS design allows low power operation without sacrificing performance. Transmit data and receive data are implemented with event driven low jitter processing. The driver of the device has an enable control line which is active HIGH.
