Absolute Maximum Ratings
Absolute maximum ratings are the values beyond which the device may be damaged or have its useful life
impaired. Functional operation under these conditions is not implied.

Notes
1. VSH must not be shorted to VSS or V+, even instantaeously, or device damage may result.
2. Using Mil Std. 883E, method 3015.7(Human Body Model), 400V when using JEDEC method A115-A (Machine Model).

Note
3 . In the test circuit, capacitors C1 and C2 are 0.2Ω maximum ESR capacitors. Capacitors with higher ESR will increase output
resistance, reduce output voltage and efficiency.
