Features and 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 SP232A is a line driver and receiver pair that meets the specifications of RS-232 and V.28 serial protocols. This device is pin-to-pin compatible with popular industry standard pinouts.

The SP232A offers 120kbps data rate under load, small ceramic type 0.1μF charge pump capacitors and overall ruggedness for commercial applications.

The SP232A features Exar's BiCMOS design allowing for low power operation without sacrificing performance. This device is available in plastic DIP, SOICW and nSOIC packages operating over the commercial and industrial temperature ranges.
