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
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.
