XR16L788 HIGH PERFORMANCE 2.97V TO 5.5V OCTAL UART

The XR16L7881 (788), is a 2.97V to 5.5V with 5V tolerant inputs octal Universal Asynchronous Receiver and Transmitter (UART). The highly integrated device is designed for 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. E.
