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 can be driven to 3.3 V or 5 V by setting V
L
at the
appropriate level. The switches are low R
ON
and can carry
the maximum 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.
Low R
ON
is achieved by using MOSFETs driven off the
+ 12 V
IN
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
