DESCRIPTION
The Si9707 offers an integrated solution for dual PC Card power interfaces that require only VCC switching. This part is ideal for systems that operate at 5 V and provide VPP from the main supply, or from a dedicated Flash RAM 12-V supply. 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. The Si9707 is available in both standard and lead (Pb)-free packages.
The Si9707 operates off the 5-V supply with built-in level shifting. The VCC 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 Si9707 to be configured for positive or negative control
