MAX907CSA+T

Overview

The MAX907CSA+T is a dual high-speed, ultra-low-power voltage comparator designed for single +5V supply operation. 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 0°C to +70°C and is housed in an 8-pin SO package. It includes built-in hysteresis for clean switching and TTL-compatible outputs.

Feature Summary

• High-speed performance with 40ns propagation delay at low power consumption
• Built-in internal hysteresis eliminates external resistor requirements
• TTL-compatible outputs require no external pullup circuitry
• Input and output short-circuit protection allows continuous connection to supply rails

Applications

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

Procurement Notes

Verify the component status as Not Recommended for New Designs due to manufacturing process availability constraints. Confirm that the specific ordering suffix matches the required temperature range and package type. Ensure compatibility with existing designs rather than new implementations. Consult technical support for potential replacement options or second-source availability if current stock is limited.

Selection Notes

Select this comparator for applications requiring fast response times combined with minimal power dissipation on a single +5V supply. The fixed internal hysteresis simplifies circuit design by removing the need for external feedback components. Verify that the operating environment stays within the specified commercial temperature limits and that the load conditions match the TTL-compatible output drive capabilities.

Part Context

This part belongs to the MAX907/MAX908/MAX909 family of comparators manufactured by Maxim Integrated (now Analog Devices). While the datasheet remains available for reference, the manufacturing process is discontinued. The MAX907 specifically provides two independent comparators in an 8-pin configuration, distinct from the quad MAX908 and the latch-equipped MAX909.

Replacement Considerations

Maxim suggests that a replacement or industry second-source may be available. Users should contact technical support for assistance in identifying suitable alternative components for new designs.
