MaxLinear | SP3485EN-L

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 SP3481 and the SP3485 are a family of +3.3V low power half-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 SP481, SP483, and SP485 devices as well as popular industry standards.

The SP3481 and the SP3485 feature Exar's BiCMOS process, allowing low power operation without sacrificing performance. The SP3481 and SP3485 meet the electrical specifications of RS-485 and RS-422 serial protocols up to 10Mbps under load.

The SP3481 is equipped with a low power Shutdown mode.
