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.
