MAX3097ECPE

Overview

The MAX3097ECPE is a triple RS-485/RS-422 receiver featuring fault-detection circuitry and dedicated fault-status outputs. It operates on a single +3V to +5.5V supply with a maximum data rate of 32Mbps. The device provides ±15kV ESD protection via Human Body Model and IEC 1000-4-2 standards. It detects open-circuit, short-circuit, low differential voltage, and common-mode range violations. The part includes a capacitor-programmable delay for the ALARMD output to prevent erroneous alarms at slow edge rates. It is housed in a 16-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violations
• Provides independent alarm outputs (ALARMA, ALARMB, ALARMZ) and a delayed general fault output (ALARMD)
• Features ±15kV ESD protection on all receiver inputs
• Includes a capacitor-programmable delay to ensure error-free operation at slow data rates

Applications

• Motor-shaft encoders
• Telecommunications systems
• Embedded systems

Procurement Notes

Verify the specific ordering suffix 'CPE' to confirm the 16-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Ensure the design requires only receivers without integrated drivers, as this component does not contain transmitters. Cross-reference the datasheet revision date to confirm electrical characteristics match the current production version.

Selection Notes

Select the MAX3097ECPE when system architecture requires separate receiver logic or when utilizing existing driver components. This part is suitable for applications needing fault detection on A, B, and Z encoder channels. Compare against the MAX3098E variants if different fault threshold sensitivities are required for specific signal integrity conditions.

Part Context

This component belongs to the MAX3097E/MAX3098E family of high-speed interface receivers. It is designed specifically for motor-control feedback loops where signal reliability is critical. The device complements Maxim's broader portfolio of RS-485/RS-422 solutions by offering integrated diagnostics in a compact form factor.

Replacement Considerations

The MAX3097EEPE serves as the industrial temperature (-40°C to +85°C) equivalent within the same package. For applications requiring different fault thresholds, consider the MAX3098E series. Verify pin compatibility before substituting with other triple receiver ICs.
