ABSOLUTE MAXIMUM RATINGS

Power Dissipation (note 3) ........................................ Internally limited

Lead Temp (soldering, 5 seconds) ............................................ 260°C

Storage Temperature Range ..................................... -65°C to +150°C

Input Supply Voltage Range ............................................. -0.3 to +30V

ESD Rating (note 4) ...................................................................... 2kV

NOTES:

Note 1: See TYPICAL APLICATIONS notes to ensure constant junction temperature, low duty cycle pulse testing used.

Note 2: All limits are at 25

°C or over the full operationg junction temperature range of -40°C to +125°C.

Note 3: The maximum power dissipation is a function of maximum junction temperature, total thermal resistance, and ambient temperature.

Note 4: Human body model, 100pF discharged through 1.5k

Ω.
