If a low current is present at input I,
output I and output II are high impedant
(safe state).
If a high current is present at input I,
output I and output II are high impedant
(safe state).
If a low current is present at input I,
output I is high impedant (safe state).
If a high current is present at input I,
output I is high impedant (safe state).
If a low current is present at input II,
output II is high impedant (safe state).
If a high current is present at input II,
output II is high impedant (safe state).
