MAX907ESA-T

Overview

The MAX907ESA-T is a dual, high-speed, ultra-low-power voltage comparator designed for single +5V supply systems. It features a typical propagation delay of 40ns with 5mV input overdrive and consumes only 3.5mW per comparator. The device operates within a temperature range of -40°C to +85°C and utilizes an 8-pin SO package. Its wide input common-mode range extends from 200mV below ground to within 1.5V of the positive rail. Outputs are TTL-compatible, eliminating the need for external pullup resistors.

Feature Summary

• Incorporates internal hysteresis to ensure clean output switching without requiring external components.
• Features TTL-compatible outputs that function without external pullup circuitry.
• Provides input and output short-circuit protection allowing continuous connection to supply rails.

Applications

• Battery-powered systems
• High-speed A/D converters
• Threshold detectors and discriminators

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix indicates tape-and-reel packaging if required for automated assembly. Check current availability status as this part may be subject to limited supply or discontinuation notices. Ensure the operating temperature range matches the application requirements before finalizing procurement.

Selection Notes

Select this comparator for applications requiring low power consumption alongside high-speed response times in single-supply environments. Consider the fixed internal hysteresis when designing circuits to prevent oscillation from slow-moving signals. Evaluate the TTL-compatible output levels against downstream logic requirements. Review absolute maximum ratings to ensure input voltages do not exceed specified limits during transient conditions.

Part Context

This component belongs to the MAX907/MAX908/MAX909 family of comparators manufactured by Maxim Integrated, now part of Analog Devices Inc. The series includes dual, quad, and single-channel variants optimized for precision and speed. These devices were engineered to replace older comparator technologies while maintaining compatibility with standard digital logic interfaces.

Replacement Considerations

The datasheet explicitly states the MAX909 was manufactured using a process no longer available and is not recommended for new designs. Consult technical support for potential replacement options or industry second-sources suitable for existing designs.
