† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under

“recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

2. The package thermal impedance is calculated in accordance with EIA/JEDEC Std JESD51, except for the through-hole packages,

which use a trace length of zero. The absolute maximum power dissipation allowed at TA = 55 C (in still air) is 1.3 W.

3. The maximum package power dissipation is calculated using a junction temperature of 1505C and a board trace length of 750 mils.

application note in the

, literature number SCBD002.
