MAX976EUA-T

Comparators Overview

The MAX976EUA-T is a dual-channel, high-speed, low-power analog comparator from the MAX976 series by Analog Devices/Maxim Integrated. It operates on a single supply voltage ranging from +2.7V to +5.5V and achieves a propagation delay of 20ns with a typical supply current of 225µA per comparator. The device features rail-to-rail push/pull outputs compatible with CMOS/TTL logic and inputs that sense down to -0.2V below ground. It includes internal hysteresis for clean switching and tolerates continuous short-circuit faults. The component is housed in an 8-pin µMAX package and functions over a temperature range of -40°C to +85°C.

Comparators Feature Summary

• Single-supply operation optimized for +3V/+5V applications
• Rail-to-rail output capability without external pull-up circuitry
• Ground-sensing inputs extending 200mV below ground
• Internal hysteresis ensures clean output switching

Comparators Applications

• Battery-powered systems
• Threshold detectors and discriminators
• IR receivers
• Digital line receivers

Comparators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'EUA' designation corresponds to the 8-pin µMAX package variant. Ensure compatibility with single-supply voltage ranges between 2.7V and 5.5V. Check for lead-free/RoHS compliance status if required by assembly specifications. Validate availability as distribution channels may list limited stock or end-of-life statuses.

Comparators Selection Notes

Select this component for space-constrained designs requiring dual comparators in a small footprint. Ideal for applications needing fast response times under 20ns with minimal power consumption. Suitable for interfacing directly with digital logic families due to rail-to-rail outputs. Consider alternative packages like SOT23 or QSOP if channel count or form factor requirements differ.

Comparators Part Context

The MAX976EUA-T belongs to the MAX976/MAX978/MAX998 family of single/dual/quad comparators. This series is designed for high-speed, low-power performance in single-supply environments. The MAX976 specifically provides two independent comparators in one package, distinguishing it from the single-channel MAX998 and quad-channel MAX978 variants within the same product line.

Comparators Replacement Considerations

Direct substitutes include other parts from the MAX976/MAX978/MAX998 family such as the MAX976ESA (SO-8 package) or MAX976EUT (SOT23 package), provided pinout and electrical characteristics match the design requirements.
