Exar Corporation XR17C158

The XR17C1581 (158) is an octal Universal Asynchronous Receiver and Transmitter (UART). The device is designed to meet the 32-bit PCI Bus and high bandwidth requirement in communication systems. The global interrupt source register provides a complete interrupt status indication for all 8 channels to speed up interrupt parsing.
