      _______________General Description
      The MAX921–MAX924 single, dual, and quad micro-
      power, low-voltage comparators feature the lowest
      power consumption available. These comparators draw
      less than 4A supply current over temperature
      (MAX921/MAX922), and include an internal 1.182V
      ±1% voltage reference, programmable hysteresis, and
      TTL/CMOS outputs that sink and source current.
      Ideal for 3V or 5V single-supply applications, the
      MAX921–MAX924 operate from a single +2.5V to +11V
      supply (or a ±1.25V to ±5V dual supply), and each
      comparator’s input voltage range swings from the
      negative supply rail to within 1.3V of the positive
      supply.
      The MAX921–MAX924’s unique output stage con-
      tinuously sources as much as 40mA. And by eliminating
      power-supply glitches that commonly occur when com-
      parators change logic states, the MAX921–MAX924
      minimize parasitic feedback, which makes them easier to
      use.
      The single MAX921 and dual MAX923 provide a unique
      and simple method for adding hysteresis without
      feedback and complicated equations, simply by using
      the HYST pin and two resistors.
