MAX9144EUD+T

Comparators Overview

The MAX9144EUD+T is a quad high-speed comparator from the MAX9140 family, optimized for 3V and 5V single-supply systems. It features rail-to-rail inputs and outputs that swing within 300mV of either supply rail without external pullup circuitry. The device offers a propagation delay of 40ns with a supply current of 150µA per comparator. It includes internal hysteresis to ensure clean switching and CMOS/TTL-compatible outputs.

Comparators Feature Summary

• Quad configuration providing four independent comparators in a single package
• Rail-to-rail input voltage range extending beyond power-supply rails
• Internal hysteresis eliminates external resistors for noise immunity
• Outputs compatible directly with CMOS and TTL logic families

Comparators Applications

• Line Receivers
• Threshold Detectors/Discriminators
• Zero-Crossing Detectors
• Sampling Circuits

Comparators Procurement Notes

Verify the specific suffix 'EUD' corresponds to the 14-pin TSSOP package and E-grade temperature rating (-40°C to +85°C). Confirm the '+T' designation indicates tape-and-reel packaging. Ensure compatibility with the required board space and thermal dissipation limits for quad-channel operation.

Comparators Selection Notes

Select this component when multiple comparator channels are needed in a compact footprint. It serves as a lower-power and higher-speed upgrade over legacy MAX944 devices. Suitable for portable equipment requiring direct interface with digital logic without additional pull-up components.

Comparators Part Context

Part of the MAX9140/MAX9141/MAX9142/MAX9144 family of low-power, high-speed comparators. While the MAX9140 is single-channel, MAX9141 adds latch/shutdown, MAX9142 is dual-channel, and MAX9144 provides four channels. All share similar electrical characteristics including 40ns delay and rail-to-rail performance.

Comparators Replacement Considerations

MAX944 is the industry-standard comparator this series upgrades.
