High voltage power ground.
Logic control input. When mode is high, logic input high turns OFF output high voltage P-Channel.
Logic control input. When mode is high, logic input high turns ON output high voltage N-Channel.
Logic enable input. Logic low enables IC.
Mode
Logic mode input. Logic low activates 200nsec deadband. When mode is low, N
IN
turns on and off the high voltage N- and
P-Channels. Pin is not used and should be connected to V

or ground.
High voltage output. Voltage swings from P
GND
to V
