MAX3098EBCEE+

Overview

The MAX3098EBCEE+T is a triple RS-422/RS-485 receiver manufactured by Analog Devices / Maxim Integrated. It operates from 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 channel, identifying open-circuit, short-circuit, low differential voltage, and common-mode range violations. It includes ±15kV ESD protection on all inputs. The component is housed in a 16-pin QSOP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Triple high-speed receivers with integrated fault detection for open circuits, short circuits, and signal anomalies
• Robust electrostatic discharge protection rated at ±15kV across multiple testing standards
• Capacitor-programmable delayed fault output to prevent erroneous alarms during slow edge rates
• Extended common-mode input range spanning -10V to +13.2V

Applications

• Motor-shaft encoder interfaces requiring A, B, and Z signal reception
• High-speed industrial communication systems utilizing RS-485 or RS-422 protocols
• Telecommunications equipment demanding reliable signal integrity
• Embedded systems operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'CEE' corresponds to the 16-pin QSOP package and the commercial temperature grade (0°C to +70°C). Confirm that the '+T' designation indicates tape-and-reel packaging if reel quantity is required for assembly. Cross-reference the manufacturer's current ordering information to ensure the part remains active and has not been superseded by a newer revision.

Selection Notes

Select this component when three distinct differential receiver channels are required alongside comprehensive fault monitoring capabilities. It serves as a direct upgrade to legacy devices like the 26LS32, offering smaller footprint and enhanced diagnostic features. Ensure the application environment stays within the specified 0°C to +70°C temperature range and utilizes a 3V to 5.5V power supply.

Part Context

This device belongs to the MAX3097E/MAX3098E family of high-speed interface receivers. While the MAX3097E provides similar functionality, the MAX3098E variant offers tighter fault-detection thresholds specifically optimized for detecting lower differential voltages. Both share identical pinouts and electrical characteristics regarding speed and ESD protection, differing primarily in their fault sensitivity parameters.

Replacement Considerations

The MAX3097EBCCEE+T is a functional substitute within the same family, sharing the same package and temperature range but featuring different fault-detection thresholds. Other variants such as MAX3098EAESE+ offer extended temperature ranges (-40°C to +85°C) and alternative packages like SO-16.
