Note 5:
Electrical characteristics, such as On-Resistance, will change when power supplies other than ±15V, are used.
Note 6:

FUNCTION
Switching Time Test Circuit
Switch output waveform shown for V
S
= constant with
logic input waveform as shown. Note that V
S
may be
+ve or -ve as per switching times 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.
Protecting Against Fault
Conditions
Fault conditions occur when power supplies are turned
off when input signals are still present, or when over-
voltages occur at the inputs during normal operation. In
either case, source-to-body diodes can be forward
biased and conduct current from the signal source. If
