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 MaxLinear’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.

FEATURES
● Full-duplex RS-485 and RS-422 transceivers
● Operates from a single 3.3V supply
● Interoperable with 5.0V logic
● Driver/receiver tri-state enable lines (SP3491)
● -7V to 12V common-mode input voltage range
● ±200mV receiver input sensitivity
● Allows up to 32 transceivers on the serial bus
● Compatability with LTC490 and SN75179 (SP3490)
● Compatability with LTC491 and SN75180 (SP3491)
