Features & Applications
EXAR, the market leader, offers the industry's broadest line-up of UART and serial protocol transceivers solutions.

With over 200 devices, wide 2.25 to 5.5V power supply range, 1 to 128 bytes of FIFO and compliance with the universal 3.3/5V PCI, Intel and Motorola bus interfaces, including single protocol ICs that support RS-232, RS-422 or RS-485 as well as dual and multi-protocol ICs that support from 2 to 8 of the most popular interface standards with a single IC, Exar has already done the difficult work for you.

We can deliver an immediate competitive advantage to your compressed time-to-market demands accelerating initial design, to functioning prototype and finally volume production.

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 Exar SP490 and SP491 devices as well as popular industry standards.

The SP3490 and the SP3491 feature Exar'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.

SP3490 Features:

  • Full Duplex RS-485 and RS-422 Transceivers
  • Operates from a single +3.3V supply
  • Interoperable with +5.0V logic
  • -7V to +12V Common-Mode Input Voltage Range
  • +200mV Receiver Input Sensitivity
  • Allows up to 32 transceivers on the serial bus
  • Compatibility with LTC490 and SN75179
