ADM1485AR Description

Short technical summary and product information.

The ADM1485AR is an RS-485/RS-422 transceiver designed for high-speed bidirectional data communication on multipoint bus lines. It integrates a differential line driver and receiver, both independently enableable, and operates from a single 5V supply.

 

Key electrical characteristics include a data rate of 30 Mbps, half-duplex operation, and a common-mode voltage range of -7V to +12V. The receiver features 70 mV hysteresis for noise immunity. Protection features include thermal shutdown, short-circuit protection, and fail-safe output that ensures a logic high when inputs are floating.

 

The device is housed in an 8-pin SOIC package with surface mount mounting. It is specified for industrial temperature range from -40°C to +85°C. The ADM1485AR is suitable for low power RS-485 systems, DTE-DCE interfaces, and local area networks.
