MAX944CSD-T

Comparators Overview

The MAX944CSD-T is a quad high-speed, low-power voltage comparator optimized for single-supply operation from 2.7V to 5.5V. It features rail-to-rail input voltage range extending beyond both power-supply rails and outputs that pull within 0.4V of either supply rail without external pullup circuitry. The device provides an 80ns propagation delay with 350µA supply current per comparator. Internal hysteresis ensures clean switching, while CMOS/TTL-compatible outputs interface directly with logic circuits.

Comparators Feature Summary

• Rail-to-rail input voltage range extending beyond supply rails
• Internal hysteresis for clean output switching
• CMOS and TTL compatible outputs

Comparators Applications

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

Comparators Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific package type and temperature rating associated with the CSD suffix. Ensure compatibility with system voltage requirements and signal integrity standards before integration into final designs.

Comparators Selection Notes

Select this component for applications requiring fast response times in portable or battery-powered systems operating at 3V or 5V. The quad configuration allows multiple comparison functions within a single package, reducing board space compared to individual units.

Comparators Part Context

This part belongs to the MAX941/MAX942/MAX944 family of comparators manufactured by Analog Devices/Maxim Integrated. The MAX944 specifically offers four independent channels in a 14-pin narrow SO package, distinguishing it from the single-channel MAX941 and dual-channel MAX942 variants.

Comparators Replacement Considerations

Direct substitutes include MAX944CSD and MAX944ESD. Verify pinout compatibility and electrical specifications when transitioning between these variants.
