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. I_D(ON) is leakage from driver into ON switch.
5. OFF Isolation = 20log _V-^V----_DS-- , V_S = Input to OFF switch, V_D = output .
Test Circuits and Waveforms
Switch output waveform shown for V_S = constant with logic
input waveform as shown. Note the V_S may be + or - as per
switching time test circuit. V_O is the steady state output with
switch on. Feedthrough via gate capacitance may result in
spikes at leading and trailing edge of output waveform.
