2 1IN- input Inverting input of comparator 1, common-mode range -0.3V to VCC.
3 1IN+ input Non-inverting input of comparator 1, common-mode range -0.3V to VCC.
4 VEE power_in Negative supply, connected to GND in single-supply operation (dual supply up to ±16V).
5 2IN+ input Non-inverting input of comparator 2, common-mode range -0.3V to VCC.
6 2IN- input Inverting input of comparator 2, common-mode range -0.3V to VCC.
7 2OUT output Open-drain output of comparator 2, with typical VOL of 0.1V at IOL=4mA.
8 VCC power_in Positive supply, 2V to 32V single supply (absolute maximum 36V).
