MAX996ESD+

Comparators Overview

The MAX996ESD+ is a quad micropower comparator from the MAX987/MAX988/MAX991/MAX992/MAX995/MAX996 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +2.5V to +5.5V and consumes only 48μA per comparator. The device features rail-to-rail inputs and outputs, with an input common-mode voltage range extending 0.25V beyond the rails. It achieves a propagation delay of 120ns at 100mV overdrive. The output stage is open-drain, capable of being pulled beyond VCC up to 6V above VEE. Internal hysteresis ensures clean switching for slow-moving signals.

Comparators Feature Summary

• Quad configuration with open-drain output stages allowing external pull-up voltages up to 6V above VEE
• Rail-to-rail input and output capabilities with common-mode range extending 0.25V beyond supply rails
• Micropower operation consuming 48μA per comparator while maintaining 120ns propagation delay
• Internal hysteresis prevents false triggering caused by slow-moving input signals

Comparators Applications

• Zero-Crossing Detectors
• Window Comparators
• Level Translators
• Threshold Detectors/Discriminators
• Ground/Supply Sensing

Comparators Procurement Notes

Verify the specific package code S14-4 corresponds to the SOIC-14 housing required for your PCB layout. Confirm that the open-drain output architecture aligns with your circuit's pull-up requirements, as it differs from push-pull variants in this series. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications before finalizing procurement.

Comparators Selection Notes

Select the MAX996ESD+ when a quad comparator with open-drain outputs is required for level shifting or interfacing with higher voltage logic lines. This part is suitable for battery-powered systems due to its low quiescent current. Consider alternative parts like the MAX995 if push-pull outputs are needed instead of open-drain configurations.

Comparators Part Context

This component belongs to the MAX987/MAX988/MAX991/MAX992/MAX995/MAX996 family of high-speed, micropower, low-voltage comparators. These devices share similar electrical characteristics but differ in channel count and output stage types. The MAX996 specifically provides four channels with open-drain outputs, distinguishing it from the push-pull versions within the same product line.

Comparators Replacement Considerations

The MAX996EUD (TSSOP-14) offers identical electrical performance in a different package format. For push-pull output requirements, the MAX995ESD+ serves as a functional equivalent with the same quad configuration.
