Product details

RS-485/RS-422 full-duplex transceiver for 5 V systems

The MAX490ECSA+T is a single-channel RS-422/RS-485 transceiver in an 8-SOIC package, supporting full-duplex communication at data rates up to 2.5 Mbps. It integrates one driver and one receiver, with 70 mV of receiver hysteresis.

Commercial temperature grade — deployment boundary

Rated 0°C to 70°C, this part is intended for office, lab, and climate-controlled industrial enclosures. It is not suited for outdoor telecom cabinets, engine bays, or freezer environments where the ambient can drop below freezing. For extended temperature needs, look at the industrial-grade variants in the same family.

Active production — no LTB risk

The MAX490ECSA+T carries an Active product status with ROHS3 compliance.

Frequently asked questions

What is the recommended PCB footprint for MAX490ECSA+T (8-SOIC)?

The 8-SOIC footprint follows the JEDEC standard for SOIC-8 (3.90 mm body width). Standard land patterns from IPC-7351 or the manufacturer's datasheet apply. No special thermal pad or via array is required for this low-power transceiver.

What is the difference between MAX490 and MAX485?

The MAX490 is a full-duplex transceiver (separate driver and receiver pins for simultaneous transmit and receive), while the MAX485 is half-duplex (shared bus lines, direction control via DE/RE). Both operate at up to 2.5 Mbps and use the same 5 V supply, but they are not pin-compatible for full-duplex designs.
