Overview
The MAX903CSA+TG035 is a high-speed, low-power single voltage comparator featuring TTL-logic outputs with active internal pull-ups. It operates from separate analog and digital supplies or a single combined supply. Key electrical parameters include an 8ns typical propagation delay at 5mV overdrive, 18mW typical power consumption per comparator at +5V, and a flexible analog supply range of +5V to +10V or ±5V. The input common-mode range includes the negative rail for ground sensing.
Feature Summary
- Features independent TTL-compatible latch inputs to hold output states when driven low.
- Provides fast propagation delay suitable for high-speed data discrimination applications.
- Supports separate analog and digital power supplies to isolate noisy digital environments.
Applications
- High-speed A/D converters
- Line receivers
- Threshold detectors
- Input trigger circuitry
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for Not Recommended for New Designs (NRND) warnings in current documentation. Ensure the specific suffix matches required temperature ranges and packaging specifications before procurement.
Selection Notes
Select this part for applications requiring fast response times and latch functionality. Consider the MAX920x series for newer designs offering pin-for-pin compatibility with reduced power dissipation. Verify that the single-channel configuration meets system requirements compared to dual or quad variants.
Part Context
This device belongs to the MAX900–MAX903 family of high-speed, low-power voltage comparators manufactured by Analog Devices Inc./Maxim Integrated. The family includes single, dual, and quad configurations with varying latch capabilities. The MAX903 specifically provides one comparator with latch inputs in an 8-pin package.
Replacement Considerations
The datasheet indicates the MAX900 was manufactured using a process no longer available and is not recommended for new designs. For newer, pin-for-pin compatible parts with similar speed but half the power dissipation, refer to the MAX9201/MAX9202/MAX9203 data sheet.
