PC Card (PCMCIA) Dual Interface Switch

Transcription

1 Product is End of Life 3/204 Si9707 PC Card (PCMCIA) Dual Interface Switch DESCRIPTION The Si9707 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 2 V supply. The Si9707 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 Si9707 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. FEATURES Single SO-6 Package CMOS Logic Compatible Inputs Smart Switching Slow V CC Ramp Times Extremely Low R ON Supports Dual PC Card Slots Reverse Blocking Switches Low Power Consumption Safe Power-Up The PC Card Dual Interface Switch is available in a SO-6 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.
