Интерфейс RS-485 и RS-422

Спецификация RS-485 соответствует требованиям многоточечной коммуникационной сети, и данный стандарт определяет присутствие до 32 драйверов и 32 приемников на одной (2-х проводной) шине. Некоторые приемопередатчики RS-485 могут изменять входной импеданс, чтобы к одной и той же шине могло подключиться в 8 раз больше узлов. Analog Devices предлагает широкий ассортимент стандартных приемопередатчиков RS-485 / RS-422 и выполненных по технологии iCoupler® изолированных приемопередатчиков RS-485 / RS-422, которые подойдут для многих приложений.
