Si9706DY Vishay Siliconix PC Card (PCMCIA) Interface Switch FEATURES D Single SO-8 Package D CMOS-Logic Compatible Inputs D Slow VCC Ramp Time D Smart Switching D Extremely Low RON D Reverse Blocking Switches D Low Power Consumption D Safe Power Up DESCRIPTION The Si9706DY offers an integrated solution for PC Card power interfaces that only require 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. 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 Si9706DY operates off the 5-V supply and has built-in level shifting for gate drive. Internal logic protects against a control logic error that would short 5 V to the 3.3-V supply. This protection logic also allows the Si9706DY to be configured for The Si9706DY PC Card interface switch is packaged in a narrow body SO-8 package and is rated over the industrial temperature range −40 to 85_C. The Si9706DY is available in lead free. FUNCTIONAL BLOCK DIAGRAM +5 VIN +3.3 VIN (7) (6) SW1 (2) SW2 (3) VCC VCC SW3 S1 S2 SR Document Number: 70010 S-40127—Rev.
