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 sup-
ply.
The Si9707 operates off the 5 V supply with built-in level
shifting. The V
CC
outputs function independently and inter-
nal 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 neg-
ative control logic for compatibility with a variety of PC Card
controllers. These control inputs are CMOS logic compati-
ble 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 tem-
perature range of - 40 to 85 °C.
The Si9707 is available in both standard and lead (Pb)-free
packages.
