The MAX976/MAX978/MAX998 dual/quad/single, high-
speed, low-power comparators are optimized for
+3V/+5V single-supply applications. They achieve a
20ns propagation delay while consuming only 225µA
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.
The MAX976/MAX978/MAX998 inputs have a common-
mode voltage range that extends 200mV below ground.
Their outputs are capable of rail-to-rail operation with-
out external pullup circuitry, making these devices ideal
for interface with CMOS/TTL logic. All inputs and out-
puts can tolerate a continuous short-circuit fault condi-
tion to either rail. The comparators’ internal hysteresis
ensures clean output switching, even with slow-moving
input signals.
For space-critical applications, the single MAX998 is
available in a 6-pin SOT23 package, the dual MAX976
is available in an 8-pin µMAX
MAX978 is available in a 16-pin QSOP package.
