DESCRIPTION
The SP3490 and the SP3491 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 Sipex SP490 and SP491 devices as well as popular industry standards.
The SP3490 and the SP3491 feature Sipex's BiCMOS process, allowing low power operation
without sacrificing performance. The SP3490 and SP3491 meet the electrical specifications
of 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 receiver tri-state enable lines.
