That doubles throughput on a point-to-point link compared to a half-duplex part at the same bit rate. ## 3.3V supply — voltage-domain planning The supply range is 3V to 3.6V, which is a strict 3.3V rail. This part is not 5V-tolerant on the supply or the bus pins. ## Package and footprint 14-SOIC narrow body (3.90 mm width). Surface-mount only. The footprint is standard SOIC-14; no thermal pad required. The tube shipping medium is fine for prototype builds; production volumes typically come on tape-and-reel — confirm the reel option when ordering if you run a pick-and-place line. ## Lifecycle and compliance ROHS3 compliant. No known PCN for die shrink or package change. This part is safe to specify into new designs without an obsolescence watch.","metaTitle":"MAX3491CSD+ RS-485/RS-422 Transceiver, Full Duplex, 10 Mbps","metaDescription":"MAX3491CSD+ is a 3V–3.6V full-duplex RS-485/RS-422 transceiver in 14-SOIC, 10 Mbps data rate.
