The constant-voltage regulated output VO (= voltage between H side output and GND) is controlled by VO = 2.5 × VC. The output
is in the saturated state when the VC input range is 0.2 to 6 V and VO ^ VCC.

IN2
IN1
Input pins that determine the excitation of
the outputs.
IN1 control outputs OUT1 and OUT2;
IN2 control outputs OUT3 and OUT4.
L: –0.3 to +0.7 V or open
