Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The MAX971MAX974 and MAX981MAX984 single/ dual/quad low-voltage comparators feature the lowest power consumption available. These micropower devices draw less than 4A supply current over temperature (MAX971/MAX972, MAX981/MAX982), and include an internal 1.182V ±1% (MAX971/MAX973/ MAX974) or ±2% (MAX981MAX984) voltage reference and programmable hysteresis.

Ideal for 3V or 5V single-supply applications, these MAX981MAX984 operate from a single +2.5V to +11V supply (or ±1.25V to ±5.5V dual supplies), and each comparator's input voltage ranges from the negative supply rail to within 1.3V of the positive supply.

The single MAX971 and MAX981 and the dual MAX973 and MAX982/MAX983 provide a unique, simple method for adding hysteresis without feedback or complicated equations, simply by using the HYST pin plus two resistors.

The MAX971MAX974 and MAX981MAX984's opendrain outputs permit wire-ORed configurations. Thanks to an 11V output range and separate GND pin for the output transistor (MAX971/MAX974, MAX981/MAX984), these MAX981MAX984 are ideal for level translators and bipolar to singleended converters.
