Description

This device consists of two independent low-

power voltage comparators designed specifically

to operate from a single supply over a wide range

of voltages. Operation from split power supplies is

also possible.

The input common-mode voltage range includes

the negative rail even though operated from a

single power supply voltage.

All the pins are protected against electrostatic

discharge up to 2 kV. As a consequence, the input
