MAX903CSA-T

Overview

The MAX903CSA-T is a high-speed, low-power single voltage comparator from the MAX900–MAX903 series. It features differential analog inputs and TTL-logic outputs with active internal pull-ups. The device includes independent TTL-compatible latch inputs to hold output states. It supports separate analog and digital power supplies or a single combined supply. Typical propagation delay is 8ns at 5mV overdrive, with power consumption of 18mW per comparator at +5V.

Feature Summary

• Features fast propagation delay for high-speed data discrimination applications
• Includes independent TTL-compatible latch inputs to freeze output states
• Supports flexible analog supply ranging from +5V to +10V or ±5V
• TTL-compatible outputs optimized for driving low-power Schottky TTL

Applications

• High-speed A/D converters
• Line receivers
• Threshold detectors
• Input trigger circuitry
• PWM circuits

Procurement Notes

Verify component authenticity through authorized distributors. Confirm package integrity and pin alignment upon receipt. Check datasheet revisions for updates. Ensure storage conditions meet manufacturer specifications. Validate electrical parameters against official test limits before integration.

Selection Notes

Select this part for designs requiring fast response times and latch functionality. Verify supply voltage compatibility with system rails. Consider thermal dissipation requirements for dense layouts. Evaluate input slew rates to prevent oscillation. Confirm temperature range suitability for the operating environment.

Part Context

This component belongs to the MAX900–MAX903 family of high-speed comparators. It is designated as Not Recommended for New Designs due to manufacturing process discontinuation. Existing users may find replacement options in the MAX920x series for lower power consumption.

Replacement Considerations

The MAX9201/MAX9202/MAX9203 are recommended replacements offering pin-for-pin compatibility with half the power dissipation.
