ISA BUS (IEEE P996)
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
at 5.0 V and 3.3 V operation. By tying the V
CCB
pin to the
card voltage supply, the PCMCIA card will always have
rail−to−rail output swings, maximizing the reliability of the
interface.
The V
CCA
pin must always be tied to a 3.3 V power supply.
This voltage connection provides internal references needed
to account for variations in V
CCB
. When connected as in the
figure above, the LVXC3245 meets all the voltage and current
requirements of the ISA bus standard (IEEE P996).
