MAX907CSA-T

Overview

The MAX907CSA-T is a dual high-speed, ultra-low-power voltage comparator designed for single +5V supply systems. It features a 40ns propagation delay with 5mV input overdrive and consumes only 3.5mW per comparator. The device operates within a 4.5V to 5.5V positive supply range and includes built-in hysteresis for clean switching. It offers TTL-compatible outputs, wide input common-mode range extending below ground, and short-circuit protection on all inputs and outputs.

Feature Summary

• Incorporates internal hysteresis to ensure clean output switching without external resistors
• Features TTL-compatible outputs requiring no external pullup circuitry
• Provides input and output short-circuit protection against continuous connection to supply rails

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Confirm the 'C' designation aligns with the commercial temperature range of 0°C to +70°C. Check current availability status as the component family may be subject to discontinuation or replacement notices from the manufacturer.

Selection Notes

Select this part for applications requiring low power consumption combined with high speed in single-supply environments. Ensure the design accommodates the fixed internal hysteresis characteristics. Verify that the 40ns propagation delay meets system timing requirements under expected capacitive load conditions.

Part Context

This component belongs to the MAX907/MAX908/MAX909 family of comparators manufactured by Analog Devices Inc./Maxim Integrated. The datasheet notes that the MAX909 was produced using an unavailable process, marking it as not recommended for new designs, though the MAX907 remains available for existing users.

Replacement Considerations

Consult technical support for Maxim replacements or industry second-sources due to potential manufacturing process changes affecting the MAX909 variant.
