DESCRIPTION

The Si9711 is a monolithic switch designed to meet the needs

of the PC Card interface. The inputs are fully CMOS

compatible and incorporate all the level shift and interface

required to be driven by any CMOS driver. The external inputs

currents found on the PC Card interface.

The 5-V and 3.3-V switches do not have the parasitic diode

found in vertical DMOS power switches.

input. All level shifting is built into the Si9711.

The Si9711 is packaged in an SO-16 package and is rated

over the commercial temperature range 0 to 70_C.

The Si9711 is available in both standard and lead (Pb)-free

packages.
