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.

NOTES:

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

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

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