Overview
The ADM489ARUZ-REEL7, produced by Analog Devices Inc., is a low-power, differential line transceiver designed for communication on multipoint bus transmission lines. It is suitable for full-duplex data transmission and complies with both EIA RS-485 and RS-422 standards. The device contains a single differential line driver and a single differential line receiver, with the ADM489 model including an additional receiver and driver enable control. This transceiver operates from a single 5 V ± 10% power supply and features a thermal shutdown circuit to prevent excessive power dissipation during fault conditions.
