Maximum Ratings

Storage temperature................................-65˚C to +150˚C

Ambient temp. with power applied ...........-65˚C to +125˚C

Soldering temperature of leads (10 seconds) ........+300˚C

ESD protection on all pins ......................................... 4 kV

*Notice: Stresses above those listed under “Maximum ratings”

may cause permanent damage to the device. This is a stress rat-

ing only and functional operation of the device at those or any

other conditions above those indicated in the operational listings

of this specification is not implied. Exposure to maximum rating

conditions for extended periods may affect device reliability.

Note 1: This parameter is tested at Tamb = 25

2: This parameter is periodically sampled and not 100% tested.

3: This parameter is not tested but guaranteed by characterization. For endurance estimates in a specific appli-

cation, please consult the Total Endurance Model which can be obtained on our BBS or website.
