DESCRIPTION

These devices consist of two independent low

voltage comparators designed specifically to oper-

ate from a single supply over a wide range of volt-

ages. Operation from split power supplies is also

possible.

These comparators also have a unique character-

istic in that the input common-mode voltage range

includes ground even though operated from a sin-

gle power supply voltage.

All the pins are protected against electrostatic dis-

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

voltages must not exceed the magnitude of Vcc+

or Vcc-.
