__________________Detailed Description
The MAX976/MAX978/MAX998 dual/quad/single com-
parators operate from a single +2.7V to +5.5V supply.
They achieve a 20ns propagation delay while consum-
ing only 225µA of supply current per comparator. The
MAX998 features a low-power shutdown mode that
places the output in a high-impedance state and
reduces supply current to 1nA. Activate shutdown
mode by driving SHDN low.
The MAX976/MAX978/MAX998 comparator inputs have
a common-mode voltage range of -0.2V to (V

Either input can be driven to the Absolute Maximum
Ratings limit without false output inversion, as long as
the other input is within the Common-Mode Voltage
Range. Their push/pull output structure is capable of
rail-to-rail operation without external pull-up circuitry,
making these devices ideal for interfacing with
CMOS/TTL logic. All inputs and outputs can tolerate a
continuous short-circuit fault condition to either supply.
The comparator’s internal hysteresis ensures clean out-
put switching, even with slow-moving input signals.
