MAX3097EEEE+

Overview

The MAX3097EEEE+ is a triple RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3V to +5.5V supply and supports data rates up to 32Mbps. The device features ±15kV ESD protection (Human Body Model, IEC 1000-4-2 Air-Gap) and an extended common-mode range of -10V to +13.2V. It includes fault detection for open circuits, short circuits, low differential voltage, and common-mode violations. The package is a 16-pin QSOP with an operating temperature range of -40°C to +85°C.

Feature Summary

• Detects open-circuit conditions, short-circuit conditions, low differential input voltage, and common-mode range violations.
• Provides independent alarm outputs for each receiver channel plus a universal delayed fault output.
• Features capacitor-programmable delay on the ALARMD pin to prevent erroneous alarms during slow edge rates.
• Offers ±15kV ESD protection on all receiver inputs without latch-up.

Applications

• Motor-shaft encoder receivers
• High-speed triple RS-485/RS-422 interfaces
• Telecommunications systems
• Embedded systems

Procurement Notes

Verify the specific suffix 'EEEE' corresponds to the -40°C to +85°C temperature range and 16-pin QSOP package. Confirm RoHS compliance status as indicated in the ordering information. Ensure the component matches the exact manufacturer part number to guarantee electrical characteristics and pinout compatibility.

Selection Notes

Select this component when three independent high-speed receivers with comprehensive fault detection are required. It is suitable for noisy industrial environments where signal integrity monitoring is critical. Compare against standard receivers if fault indication or extended common-mode ranges are necessary for the application design.

Part Context

This component belongs to the MAX3097E/MAX3098E family of triple RS-422/RS-485 receivers. The MAX3097E variant specifically provides fault detection thresholds optimized for detecting lower differential voltages compared to the MAX3098E. Both share similar packaging and operational parameters but differ in specific alarm threshold settings.
