Working Principles

The ISL83387EIVZ acts as an interface between microcontrollers or other digital devices and the RS-485/RS-422 communication bus. It converts the digital signals from the microcontroller into differential voltage signals suitable for transmission over long distances.

The transceiver employs a differential line driver to transmit data and a differential receiver to receive data. The driver amplifies the digital signals and converts them into balanced differential voltages, while the receiver detects and decodes the received differential signals back into digital form.

The IC also incorporates features such as driver output enable (DE) and receiver output enable (RE), which allow control over the direction of data flow on the bus.
