Special Considerations
In certain applications the external load-resistor current
may include both V
CC
and signal line components. To
avoid drawing V
CC
current when switch current flows into
the analog switch pins, the voltage drop across the switch
must not exceed 1.2V (calculated from the ON resistance).
