XR17C154 Overview
The XR17C1541 (154) is a quad PCI Bus Universal Asynchronous Receiver and Transmitter (UART) with same package and pin-out as the Exar XR17x158 octal UARTs. The device is designed to meet today’s 32-bit PCI Bus and high bandwidth requirements in munication systems. The global interrupt source register provides a plete interrupt status indication for all 4 channels to speed up interrupt parsing.
