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
level. The switches are low R
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.
