Working Principles

The ADM3073EYRZ is a low-power RS-485/RS-422 transceiver that facilitates bidirectional communication between two or more devices. It operates by converting the logic-level signals from the driver inputs into differential voltage signals on the A and B lines, which are then received and converted back into logic-level signals by the receiver outputs.

The driver output enable (DE) and receiver output enable (RE) pins allow the user to control the direction of data flow. When DE is high and RE is low, the device is in transmit mode, allowing data to be sent from the driver inputs (DI) to the A and B lines. Conversely, when DE is low and RE is high, the device is in receive mode, enabling the receiver outputs (RO) to capture and convert incoming data.

The ADM3073EYRZ also incorporates ESD protection, safeguarding the device against electrostatic discharges that can occur during handling or in harsh industrial environments.
