DESCRIPTION
The Si9707DY offers an integrated solution for dual PC Card
power interfaces that require only V_CC switching. This part is
ideal for systems that operate at 5 V and provide V_PP from the
main supply, or from a dedicated Flash RAM 12-V supply.
The Si9707DY operates off the 5-V supply with built-in level
shifting. The V_CC outputs function independently and internal
logic protects each slot against a control logic error that would
short 5 V to the 3.3-V supply. This protection logic also allows
the Si9707DY to be configured for positive or negative control
logic for compatibility with a variety of PC Card controllers.
These control inputs are CMOS logic compatible and can be
driven to 3.3 V or 5 V.
The PC Card Dual Interface Switch is available in a SO-16
narrow-body package and is rated over the industrial
temperature range of -40 to 85°C.
