Product Summary
The XR16L788IQ is a 5V and 3.3V with 5V tolerant inputs octal Universal Asynchronous Receiver and Transmitter (UART). The highly integrated device is designed for high bandwidth requirement in communication systems. A new feature increases the XR16L788IQ driver efficiency includes a global interrupt pin with global interrupt source registers that provide complete and detailed interrupt status information for all 8 channels that will speed up interrupt parsing. The applications of the XR16L788IQ include Remote Access Servers, Ethernet Network to Serial Ports, Network Management, Factory Automation and Process Control, Point-of-Sale Systems, Multi-port RS-232/RS-422/RS-485 Cards.
