3	INA+	input	Comparator A noninverting input with common-mode range of -0.2V to (VCC - 1.2V).
4	GND	power_in	Ground.
5	INB+	input	Comparator B noninverting input with common-mode range of -0.2V to (VCC - 1.2V).
6	INB-	input	Comparator B inverting input with common-mode range of -0.2V to (VCC - 1.2V).
7	OUTB	output	Comparator B push/pull rail-to-rail output that tolerates continuous short-circuit to either supply.
