Product details

Full-duplex RS-485/RS-422 transceiver, 10 Mbps

The MAX3291ESD+: It hits 10 Mbps on the bus — fast enough for multi-drop industrial links where every microsecond of latency on a sensor read costs a cycle. The part is surface-mount only, soldered into a 14-SOIC (150-mil body) footprint.
