SI9707 vishay siliconix document number: 70018 s-40744?rev. f, 19-apr-04 www.vishay.com 1 pc card (pcmcia) dual interface switch features single so-16 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 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 12-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. 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. functional block diagram (9) sra +5 v ina +3.3 v ina v cca v cca s 1a s 2a level shift and drivers sw 1a sw 2a (12) (11) (5) (6) (10) (7) sw 3a (16) srb +5 v inb +3.3 v inb v ccb v ccb s 1b s 2b level shift and drivers sw 1b sw 2b (13) (14) (4) (3) (15) (2) sw 3b gnd (1, 8)
