MAX902CSD+

Overview

The MAX902CSD+ is a high-speed, low-power dual 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 operates from separate analog and digital supplies or a single combined supply (+5V to +10V). Key electrical parameters include an 8ns typical propagation delay at 5mV overdrive, 18mW power consumption per comparator at +5V, and an input common-mode range that includes the negative rail.

Feature Summary

• Features fast propagation delay for high-speed data discrimination applications
• Includes independent TTL-compatible latch inputs to hold comparator output states
• Supports flexible analog supply voltages ranging from +5V to +10V or ±5V
• Analog input common-mode range includes the negative supply rail for ground sensing

Applications

• Fast A/D converters and sampling circuits
• Line receivers
• Voltage-to-frequency (V/F) converters
• Threshold detectors and input trigger circuitry
• PWM circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may indicate temperature ranges or packaging variations. Ensure design compatibility with existing layouts as this part is marked Not Recommended for New Designs.

Selection Notes

Select this component for legacy designs requiring high-speed comparison with latching capabilities. Consider the MAX9201/MAX9202/MAX9203 series for newer projects seeking pin-for-pin compatibility with reduced power dissipation. Verify supply voltage requirements match the +5V to +10V analog range and ensure TTL logic levels are compatible with the output stages.

Part Context

The MAX902CSD+ belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices Inc./Maxim Integrated. This series provides single, dual, and quad configurations with similar performance characteristics. The MAX902 specifically offers two comparators with latch functionality in a 14-pin package.

Replacement Considerations

The MAX9201/MAX9202/MAX9203 series serves as a recommended replacement for new designs, offering pin-for-pin compatibility with half the power dissipation while maintaining similar speed performance.
