Description

The SP3490 and SP3491 devices are 3.3V low power full-duplex transceivers that meet the specifications of the RS-485 and RS-422 serial protocols. These devices are pin-to-pin compatible with the MaxLinear SP490 and SP491 devices as well as popular industry standards. The SP3490 and SP3491 feature MaxLinearâ€™s BiCMOS process, allowing low power operation without sacrificing performance. The SP3490 and SP3491 meet the electrical specifications of the RS-485 and RS-422 serial protocols up to 10Mbps under load. The SP3491 is identical to the SP3490 with the addition of driver and reciveiver tri-state enable lines.
