MAX3491CSD Description

Short technical summary and product information.

The MAX3491CSD is a 3.3V, low-power transceiver designed for RS-485 and RS-422 communication. It features one driver and one receiver, supporting full-duplex communication at data rates up to 10Mbps. The device operates from a single 3.3V supply and is interoperable with +5V logic.

 

Key electrical characteristics include a supply voltage range of 3V to 3.6V, a maximum data rate of 10Mbps, and a receiver hysteresis of 50mV. It supports both RS422 and RS485 protocols. The transceiver is designed with current-limiting and thermal shutdown protection for driver overload.

 

This transceiver is housed in a 14-SOIC package and features surface mount mounting type. It operates within a temperature range of 0°C to 70°C. The MAX3491CSD allows up to 32 transceivers on the bus and offers a common-mode input voltage range of -7V to +12V.
