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
Exar SP490 and SP49 devices as well as popular industry standards.
The
SP3490 and SP3491 feature Exar'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 0Mbps under load. The
SP3491 is identical
to the
SP3490 with the addition of driver and reciveiver tri-state enable lines.
