Product details

14-SOIC RS-485 transceiver with full-duplex bus

The MAX489ESD+ is a single RS-422/RS-485 transceiver in a 14-SOIC surface-mount package, supporting full-duplex communication on a single differential pair per direction. Rated for 250 kbps data rate with one driver and one receiver, it fits point-to-point or multi-drop RS-485 networks where the bus does not need direction switching.

Package and board integration

Supplied in tube packaging; the SOIC-14 body is MSL1 (moisture sensitivity level 1) by default for this class, so no dry-bake required before reflow.

RoHS3 compliant (2011/65/EU + 2015/863), with no restricted substances above the threshold limits. Suitable for EU-market equipment and lead-free reflow processes.
