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. All voltage values are with respect to the network ground terminal.
2. This rating is specified at duty = 10% on output rise and fall each pulse. Each pulse width (rise and fall) for the peak current should
not exceed 2
s.
3. See Dissipation Rating Table for free-air temperature range above 25
°C.
