MAX3098EBESE

Overview

The MAX3098EBESE is a triple RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of +3V to +5.5V and supports data rates up to 32Mbps. The device features fault-detection circuitry with independent alarm outputs for each receiver channel, identifying open-circuit, short-circuit, low differential voltage, and common-mode range violations. It provides ±15kV ESD protection via the Human Body Model and IEC 1000-4-2 standards. The component is housed in a 16-pin SO package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Detects open-circuit, short-circuit, low differential voltage, and common-mode range violations with dedicated alarm outputs
• Provides robust electrostatic discharge protection rated at ±15kV (Human Body Model) and ±15kV (IEC 1000-4-2 Air-Gap)
• Features a capacitor-programmable delayed fault output to prevent erroneous alarms during slow signal edge rates

Applications

• Motor-shaft encoder receivers
• Telecommunications systems
• Embedded systems requiring high-speed differential signaling

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm the exact package type and temperature grade. Confirm RoHS compliance status through current datasheets or distributor declarations before procurement. Ensure the selected variant matches the required industrial temperature range and physical footprint for the target PCB layout.

Selection Notes

Select this component when designing systems that require simultaneous monitoring of three differential signal lines for integrity faults. The integrated fault detection eliminates the need for external monitoring logic. Verify that the application environment does not exceed the specified common-mode input voltage limits of -10V to +13.2V to ensure accurate fault reporting.

Part Context

This part belongs to the MAX3097E/MAX3098E family of high-speed receivers designed for harsh environments. While the MAX3097E offers different fault thresholds, the MAX3098E provides specific sensitivity levels suitable for detecting lower differential voltages. Both share identical pinouts and packaging options, facilitating direct interchangeability in designs where threshold differences are acceptable.
