Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
VC = 4V sets VOUT to 24V (absolute maximum level on VSW); VC must be ≤ VIN – 200mV.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
