DESCRIPTION

The Si9712 combines low on-resistance with slow ramp time

and smart switching for overall best performance in integrated

PC Card interface switches.

The Si9712 operates off the 5-V supply and has built-in level

shifting for gate drive. Internal logic protects against an

external control input error that would short 5 V to the 3.3-V

supply. This protection logic also allows the Si9712 to be

configured for positive or negative control logic for

compatibility with a variety of PC Card controllers. These

control inputs are CMOS logic compatible and can be driven

to 3.3 V or 5 V.

The Si9712 complies with the release of the PC Card standard

programmable with an external capacitor connected to the SR

pin.

The PC Card switch is packaged in a narrow body SO-16

package and is rated over the industrial temperature range

−40 to 85_C.

The Si9712 is available in both standard and lead (Pb)-free

packages.
