MAX984CSE+TG126

Comparators Overview

The MAX984CSE+TG126 is a quad low-voltage comparator from the Maxim Integrated MAX971–MAX974/MAX981–MAX984 family. It operates on single supplies from 2.5V to 11V or dual supplies of ±1.25V to ±5.5V. The device features open-drain outputs with a separate GND pin for level translation and includes an internal 1.182V voltage reference with ±2% accuracy. It draws less than 8.5µA supply current, offers 12µs propagation delay at 10mV overdrive, and supports input common-mode ranges extending to the negative rail.

Comparators Feature Summary

• Ultra-low quiescent current consumption suitable for battery-powered systems
• Internal precision bandgap voltage reference for threshold detection applications
• Open-drain outputs with separate ground pin enabling wire-OR configurations and level shifting
• Input voltage range extends from the negative supply rail to within 1.3V of the positive rail

Comparators Applications

• Battery-powered threshold detectors
• Window comparators for undervoltage/overvoltage monitoring
• Level translators between bipolar and single-ended signals
• Oscillator circuits requiring low power consumption

Comparators Procurement Notes

Verify the specific suffix '+TG126' against official manufacturer documentation to confirm tape-and-reel packaging and lot traceability details. Ensure the component matches the commercial temperature range (0°C to +70°C) required for your application environment. Cross-reference the ordering information in the datasheet to validate the exact package type and lead finish specifications before procurement.

Comparators Selection Notes

Select this component when ultra-low power consumption is critical for battery life extension. The quad configuration allows multiple comparison functions in a single package, reducing board space. The separate output ground pin facilitates interfacing with different logic levels. Verify that the required hysteresis can be implemented using external resistors, as this specific variant lacks internal programmable hysteresis circuitry found in other family members.

Comparators Part Context

This part belongs to the MAX971–MAX974/MAX981–MAX984 series of micropower comparators designed for low-voltage operation. The '984' designation indicates a quad configuration with a 2% accurate internal reference. The 'CSE' suffix denotes a 16-pin Narrow SOIC package operating in the commercial temperature range. This family is engineered for applications demanding minimal standby current while maintaining reliable switching performance.

Comparators Replacement Considerations

The MAX974CSE serves as a direct functional substitute with a 1% reference accuracy. For extended temperature range requirements, consider the MAX974ESE or MAX984ESE variants. Devices like the MAX921–MAX924 offer complementary output stages if sourcing capability is needed.
