MAX976/MAX978/MAX998

Single/Dual/Quad, SOT23, Single-Supply,

High-Speed, Low-Power Comparators

________________General Description

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® package, and the quad

MAX978 is available in a 16-pin QSOP package.
