6 / 8 page www.fairchildsemi.com 6 Configurable I/O Application for PCMCIA Cards Block Diagram The LVXC4245 is a 24-pin dual supply device well suited for PCMCIA configurable I/O applications. Ideal for low power notebook designs, the LVXC4245 consumes less than 1 mW of quiescent power in all modes of operation. The LVXC4245 meets all PCMCIA I/O voltage require- ments at 5V and 3.3V operation. By tying VCCB of the LVXC4245 to the card voltage supply, the PCMCIA card will always experience rail to rail output swings, maximizing the reliability of the interface. The VCCA pin on the LVXC4245 must always be tied to a 5V power supply. This voltage connection provides internal references needed to account for variations in VCCB. When connected as in the block diagram above, the LVXC4245 meets all the voltage and current requirements of the ISA bus standard (IEEE P996). |
