Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality

should not be assumed, damage may occur and reliability may be affected.

1. Refer to ELECTRICAL CHARACTERISTICS and APPLICATION INFORMATION for Safe Operating Area.

2. With 100−k

W minimum input series resistance, −0.3 V to 15 V with low impedance.

3. With 10−k

W minimum input series resistance, −0.3 V to 80 V with low impedance.

4. All pins except RTN pin which is specified up to 1.0 kV.
