Configurable I/O Application for PCMCIA Cards

The 74LVXC3245 is a dual−supply device well suited for

PCMCIA configurable I/O applications. The LVXC3245

consumes less than 1mW of quiescent power in all modes of

operation, making it ideal for low power notebook designs.

The LVXC3245 meets all PCMCIA I/O voltage requirements

card voltage supply, the PCMCIA card will always have

rail−to−rail output swings, maximizing the reliability of the

interface.

This voltage connection provides internal references needed

figure above, the LVXC3245 meets all the voltage and current

requirements of the ISA bus standard (IEEE P996).
