description

The PCI950 is an IRQSER interrupt deserializer that interfaces with existing and future TI PC Card controllers.

The PCI950 accepts the IRQSER output of a TI PC Card controller and converts it to 16 ISA-style interrupts

and 4 PCI-style interrupts. Interfacing the PC Card controller with the PCI950 permits system access of all

available interrupts and features of the PC Card controller.
