MAX942CUA+T

Comparators Overview

The MAX942CUA+T is a dual high-speed comparator from the MAX941/MAX942/MAX944 family, optimized for 3V and 5V single-supply systems. It features rail-to-rail inputs extending beyond supply rails and outputs that pull within 0.4V of either rail without external pullups. The device operates with a supply voltage range of 2.7V to 5.5V, drawing 350µA per comparator at 3V. Key electrical parameters include an 80ns propagation delay (at 5mV overdrive), 1mV typical offset voltage, and internal hysteresis for clean switching. It is housed in an 8-pin µMAX package.

Comparators Feature Summary

• Rail-to-rail input voltage range extending beyond both power-supply rails
• Internal hysteresis ensures clean output switching without external resistors
• Outputs swing within 200mV of power rails, compatible with CMOS and TTL logic
• Optimized for low-power operation in portable 3V/5V applications

Comparators Applications

• Threshold detectors and discriminators
• Line receivers
• Zero-crossing detectors
• Sampling circuits

Comparators Procurement Notes

Verify the specific suffix 'CUA+T' against official documentation to confirm the component meets the commercial temperature range (-40°C to +85°C) and tape-and-reel packaging format. Ensure compatibility with the 8-pin µMAX footprint during procurement planning.

Comparators Selection Notes

Select this part for designs requiring fast response times with minimal power consumption in constrained space. The dual-channel configuration supports differential sensing or independent threshold monitoring. Verify that the 80ns propagation delay aligns with system timing requirements.

Comparators Part Context

This component belongs to the MAX94x series of high-speed comparators manufactured by Analog Devices (Maxim Integrated). The series includes single (MAX941), dual (MAX942), and quad (MAX944) variants sharing similar electrical characteristics but differing in channel count and pin configurations.

Comparators Replacement Considerations

Direct substitutes within the same family include MAX942CSA (SO package) and MAX942EUA-T (extended temperature µMAX). Cross-family replacements require matching propagation delay and supply voltage specifications.
