Applications Information
In applications where Vsw could exceed the absolute
maximum
rating
of
VCC+0.3 V,
the
following
recommendations help maintain low power consumption
and protect the part.
The addition of the series diode in the VCC supply line
blocks any current that might leak back into VCC for
over-voltage input cases.
Because the deselected channel may no longer provide
guaranteed off isolation, consider the following:
During USB transfer, the audio amplifier should be
powered down.
During audio transfer, the USB pull-up resistor
supply must be removed (as specified on page 141
of the USB 2.0 specification)
.

VCC
RECOMMENDATION
Add a low forward voltage
I
CC blocking diode to stop
current flow into the VCC pin
EXPLANATION
Parasitic PMOS bulk diode
provides a leakage path in an
over-voltage condition
RECOMMENDATION
Ensure that any voltage present
on the un-selected ports is
< VCC to prevent data
corruption on the common port
EXPLANATION
Both common port inputs have
power-off protection, allowing
them to withstand voltages
greater than 0V when V
CC = 0V
