XR17D154 - UNIVERSAL (3.3V AND 5V) PCI BUS QUAD UART

XR17D154 UNIVERSAL (3.3V AND 5V) PCI BUS QUAD UART

• REV. 1.2.2 The XR17D1541 (D154) is a quad PCI Bus Universal Asynchronous Receiver and Transmitter (UART) with same package and pin-out as the Exar XR17C158, XR17D158 and XR17C154. The device is designed to meet today’s 32-bit PCI Bus and high bandwidth requirement in communication systems. The global interrupt source register provides a complete interrupt status indication for all 4 channels to speed up interrupt parsing. Each UART is independently controlled and has its own 16C550 compatible.
