MAX3097EEPE

Overview

The MAX3097EEPE 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 fault-detection circuitry with independent alarm outputs for each receiver and a delayed general fault output. It provides ±15kV ESD protection via Human Body Model, ±15kV IEC 1000-4-2 Air-Gap, and ±8kV Contact Discharge ratings. The component is housed in a 16-pin Plastic DIP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Detects open-circuit conditions, short-circuit conditions, low differential voltage signals, and common-mode range violations.
• Includes a capacitor-programmable delay for the ALARMD output to prevent erroneous fault indications at slow edge rates.
• Offers extended common-mode input range from -10V to +13.2V.

Applications

• Motor-shaft encoders
• Telecommunications systems
• Embedded systems

Procurement Notes

Verify the specific ordering suffix EEPE confirms the -40°C to +85°C temperature range and 16-pin Plastic DIP package configuration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before procurement.

Selection Notes

Select this component when high-speed triple receiver functionality with integrated fault detection is required. Ensure the application environment necessitates the specified ±15kV ESD protection levels and the -40°C to +85°C industrial temperature rating.

Part Context

This part belongs to the MAX3097E/MAX3098E series of high-speed receivers. The MAX3097E variant specifically provides three receivers, whereas the MAX3098E includes four. Both share identical fault detection capabilities and ESD protection specifications.

FAQ

How is the delayed fault output time configured?

The ALARMD output delay is set by connecting a capacitor between the DELAY pin and GND. The delay duration depends on the supply voltage and the capacitance value.

What happens to the receiver output during a fault condition?

When a fault is detected, the corresponding ALARM_ output goes high, and the associated receiver output (OUT_) becomes indeterminate.

Does the device require external pull-up resistors for fault outputs?

No, the fault outputs are active push-pull and do not require external pull-up resistors.
