Oscillator Duty Cycle

Note 1.

Exceeding the absolute maximum rating may damage the device.

Note 2.

The device is not guaranteed to function outside its operating rating.

Note 3.

C = 4V sets VOUT to 24V (absolute maximum level on VSW); VC must be ≤ VIN – 200mV.

Note 4.

Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
