MAX3098EACEE+

Overview

The MAX3098EACEE+ 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 channel, identifying open-circuit, short-circuit, low differential voltage, and common-mode range violations. It includes a capacitor-programmable delayed fault output (ALARMD) to prevent erroneous alarms during slow edge rates. ESD protection is rated at ±15kV via Human Body Model and IEC 1000-4-2 standards. 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-circuit, short-circuit, and signal threshold anomalies
• Capacitor-programmable delayed fault output to ensure error-free operation at slow data rates
• Extended electrostatic discharge protection meeting ±15kV HBM and IEC 1000-4-2 standards
• Compact 16-pin QSOP package offering reduced footprint compared to industry-standard solutions

Applications

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

Procurement Notes

Verify the specific suffix 'ACEE' corresponds to the 0°C to +70°C temperature range and 16-pin QSOP package configuration. Confirm that the '+' designation indicates compliance with current environmental directives. Ensure the source documentation matches the exact part number to avoid confusion with B-grade variants or different package types within the same family.

Selection Notes

Select this component when designing motor-control feedback systems that require simultaneous monitoring of three differential channels. The built-in fault detection eliminates the need for external logic to identify cable breaks or shorts. Verify that the system's common-mode voltage remains within the -10V to +13.2V range to ensure accurate fault indication and proper receiver operation.

Part Context

This device belongs to the MAX3097E/MAX3098E series of high-speed interface receivers. It is specifically engineered for motion-control applications where signal integrity is critical. The MAX3098 variant provides three receiver channels, distinguishing it from the dual-channel MAX3097. The technology utilizes CMOS processes to achieve low power consumption while maintaining high-speed performance.
