MAX997EUA+T

Comparators Overview

The MAX997EUA+T is a single-channel, ultra-high-speed comparator from the MAX961–MAX999 family. It operates on a single +3V or +5V supply with a supply current of 5mA per comparator. The device features a Beyond-the-Rails input common-mode voltage range extending 100mV beyond the rails and outputs capable of sourcing or sinking 4mA to within 0.52V of GND and VCC. Propagation delay is 4.5ns with 5mV overdrive. It includes internal hysteresis and a shutdown mode consuming only 270μA. The component is housed in an 8-pin μMAX package.

Comparators Feature Summary

• Ultra-fast propagation delay for high-speed signal processing
• Beyond-the-Rails input voltage range for flexible interfacing
• Internal hysteresis for clean switching without external resistors
• Shutdown mode for low-power standby operation

Comparators Applications

• Single 3V/5V systems
• Portable/battery-powered systems
• Threshold detectors/discriminators
• GPS receivers
• High-speed sampling circuits

Comparators Procurement Notes

Verify the specific ordering suffix matches the required package type and RoHS compliance status. Confirm that the E-grade temperature rating aligns with the intended operating environment. Ensure the datasheet revision corresponds to the latest electrical characteristics before finalizing procurement specifications.

Comparators Selection Notes

Select this component when a single comparator with ultra-fast response time is required. It is suitable for applications needing Beyond-the-Rails inputs and low-voltage single-supply operation. Consider the shutdown feature if power conservation during idle periods is necessary. Verify that the 8-pin μMAX package fits the available board space constraints.

Comparators Part Context

The MAX997 is part of the MAX961–MAX964/MAX997/MAX999 family of comparators. This family offers single, dual, and quad configurations. The MAX997 specifically provides a single channel with a shutdown pin. Other family members include the MAX961 with latch enable and complementary outputs, and the MAX999 in a smaller SOT23 package.

Comparators Replacement Considerations

Direct replacements within the same family include the MAX997ESA (SO package). For different package requirements, verify pin compatibility. No other cross-family substitutes are confirmed by public documentation.
