Special Considerations
In certain applications the external load-resistor current may
include both V
DD
and signal-line components To avoid
drawing V
DD
current when switch current flows into IN OUT
pin the voltage drop across the bidirectional switch must
not exceed 0 6V at T

current will flow
through R

if the switch current flows into OUT IN pin
