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 outputs can tolerate a continuous short-circuit fault condition to either rail. The COMPARATORS’ internal hysteresis ensures clean output switching, even with slow-moving input signals.
