NOTES:

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

5. For design reference only, not 100% tested.

6. ID(ON) is leakage from driver into ON switch.

Test Circuits and Waveforms

Switch output waveform shown for VS = constant with logic

input waveform as shown. Note the VS may be + or - as per

switching time test circuit. VO is the steady state output with

switch on. Feedthrough via gate capacitance may result in

spikes at leading and trailing edge of output waveform.
