نظرة عامة على المنتج
The Analog Devices ADM2587EBRWZ is a fully integrated signal and power isolated RS-485/RS-422 transceiver with ±15kV ESD protection. It integrates a 3-channel iCoupler digital isolator, a tri-state differential line driver, a differential input receiver, and an isoPower isolated DC-to-DC converter in a single 20-lead wide-body SOIC package. The ADM2587E supports data rates up to 500kbps and operates from 3.3V or 5V single supply.
