ADM487EARZ General Description

The ADM487EARZ product line, including the ADM485E and ADM1487E models, offers cutting-edge technology and unparalleled performance in the realm of data transceivers. Ideal for applications requiring reliable half-duplex communication on multipoint bus transmission lines, these transceivers feature a robust ±15 kV ESD protection mechanism that ensures operational stability in harsh environments. Compliant with TIA/EIA standards RS-485 and RS-422, the ADM487EARZ devices guarantee seamless integration into existing communication systems. The ADM487E and ADM1487E variants stand out for their impressive ability to support up to 128 transceivers on a bus, thanks to their 1/4 unit load receiver input impedance. In comparison, the ADM485E model can accommodate up to 32 transceivers on a single bus, making it a versatile choice for smaller-scale applications. The transceivers' intelligent driver management system ensures that only one driver is active at a time, preventing bus overload and enhancing overall system efficiency. With its advanced features and reliable performance, the ADM487EARZ product line is a standout choice for demanding communication environments
