Note 2: It is recommended to avoid output switching conditions where the negative-going spikes at the VS

node would decrease VS below ground by more than -5 V.

Note 3: Enough current should be supplied to the VCC pin of the IC to keep the internal 15.6 V zener diode

clamping the voltage at this pin.
