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 SP202E/232E/233E/310E/312E devices are a family of line driver and receiver pairs that meet the specifications of RS-232 and V.28 serial protocols with enhanced ESD performance.  The ESD tolerance has been improved on these devices to over ±15KV for both Human Body Model and IEC1000-4-2 Air Discharge Method.

These devices are pin-to-pin compatible with Exar’s SP232A/233A/310A/312A devices as well as popular industry standards. As with the initial versions, the SP202E/232E/233E/310E/312E devices feature at least 120Kbps data rate under load, 0.1µF charge pump capacitors, and overall ruggedness for commercial applications. 

This family also features Exar’s BiCMOS design allowing low power operation without sacrificing performance. The series is available in plastic DIP and SOIC packages operating over the commercial and industrial temperature ranges.
