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

negative rail even though operated from a single

power supply voltage.

All

pins

are

protected

against

electrostatic

discharge up to 2 kV. Consequently, the input

+
