NOTES:

3. V

IN

= input voltage to perform proper function.

4. The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.

5. Typical values are for DESIGN AID ONLY, not guaranteed nor subject to production testing.

is the steady state output with the switch on. Feedthrough via switch capacitance may result in spikes at the leading and trailing

edge of the output waveform.
