2 IN1- input Comparator 1 inverting input; input voltage range (GND - 100mV) to (V+ + 100mV)
3 IN1+ input Comparator 1 non-inverting input; input voltage range (GND - 100mV) to (V+ + 100mV)
4 GND power_in Ground and negative power supply connection
5 IN2+ input Comparator 2 non-inverting input; input voltage range (GND - 100mV) to (V+ + 100mV)
6 IN2- input Comparator 2 inverting input; input voltage range (GND - 100mV) to (V+ + 100mV)
7 OUT2 tri_state Comparator 2 open-drain output; maximum sink current to GND 100 mA
8 V+ power_in Positive power supply; operating voltage range 1.65V to 5.5V
