MAX3097EEPE+

Overview

The MAX3097EEPE+ is a triple RS-422/RS-485 receiver featuring integrated fault-detection circuitry and dedicated alarm outputs. It operates on a single +3V to +5.5V supply with a typical current of 4mA. The device supports data rates up to 32Mbps and provides ±15kV ESD protection via Human Body Model, IEC 1000-4-2 Air-Gap, and ±8kV Contact Discharge standards. It detects open-circuit, short-circuit, low differential voltage, and common-mode range violations. The package is a 16-pin Plastic DIP (PDIP), and the operating temperature range is -40°C to +85°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violations
• Provides independent fault outputs for each receiver channel plus a delayed general fault output
• Includes capacitor-programmable delay to prevent erroneous alarms at slow edge rates
• Offers extended common-mode input range from -10V to +13.2V

Applications

• Motor-shaft encoders requiring A, B, and Z signal reception
• Telecommunications systems utilizing RS-485/RS-422 interfaces
• Embedded systems demanding high-speed data transmission with fault monitoring

Procurement Notes

Verify the specific ordering suffix 'EEPE+' corresponds to the required 16-pin PDIP package and the industrial temperature range of -40°C to +85°C. Confirm that the component meets RoHS compliance requirements for the intended assembly process. Ensure the application design accommodates the specified absolute maximum ratings for supply voltage and input signals to maintain device reliability.

Selection Notes

Select this component when a triple receiver configuration with comprehensive fault detection is required for RS-485 or RS-422 networks. It is suitable for applications needing high ESD immunity and operation across a wide common-mode voltage range. Consider the PDIP package constraints if surface-mount alternatives are not feasible for the mechanical design.

Part Context

This part belongs to the MAX3097E/MAX3098E family of high-speed receivers. The MAX3097E variant specifically provides three receivers with fault detection, whereas the MAX3098E offers similar functionality but with different fault threshold characteristics. Both share the same pinout and core features, differing primarily in the sensitivity settings for differential fault detection.

Replacement Considerations

The MAX3098E series serves as a functional alternative within the same family, offering identical pinouts and packaging options. Designers should verify that the specific fault threshold parameters of the replacement variant align with the system's noise margins and detection requirements.
