Temperature Under Bias .................... -55°C to +125°C
Storage Temperature.......................... -65°C to +150°C
Terminal Voltage with Respect to GND:
VI & VO Inputs ……………….………..…..-0.3V to 7.0V
VGATE Outputs………………………………..……...16V
All Others .........……………………………..-0.3V to 7.0V
Output Short Circuit Current .....………………….100mA
Lead Solder Temperature (10 secs) .....………….300°C
Junction Temperature.........................….......…...150°C
ESD Rating per JEDEC…………………………..2000V

Note - The device is not guaranteed to function outside its operating
rating. Stresses 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
outside those listed in the operational sections of the specification is
not implied. Exposure to any absolute maximum rating for extended
periods may affect device performance and reliability. Devices are
ESD sensitive. Handling precautions are recommended.
RECOMMENDED OPERATING CONDITIONS
