1 Do not exceed the maximum thermal junction temperature: see power de-rating curve.

2 Short circuit protection is not intended for continuous operation and is tested using pulses.

3 The power on delay is the time that is necessary before the output signal is valid

4 The maximum spec limit for this parameter is equivalent to ICC(max)+ 3 mA
