MAX3098EBEPE

Overview

The MAX3098EBEPE is a triple RS-422/RS-485 receiver featuring fault-detection circuitry and independent fault-status outputs. It operates on a single +3V to +5.5V supply with a maximum data rate of 32Mbps. The device provides ±15kV ESD protection via Human Body Model and IEC 1000-4-2 standards. It detects open-circuit, short-circuit, low differential voltage, and common-mode range violations. The part includes a capacitor-programmable delay for the ALARMD output to prevent erroneous alarms at slow edge rates. It is housed in a 16-pin Plastic DIP package and supports an operating temperature range from -40°C to +85°C.

Procurement Notes

Verify the specific ordering suffix 'BEPE' corresponds to the -40°C to +85°C temperature range and 16-pin Plastic DIP package configuration. Confirm that the 'B' grade designation aligns with the required fault detection threshold specifications for your application design.

Selection Notes

Select this component when high-speed triple reception up to 32Mbps is required alongside comprehensive fault monitoring. Ensure the system benefits from the extended common-mode input range of -10V to +13.2V and the programmable delay feature for noisy industrial environments.

Part Context

This part belongs to the MAX3097E/MAX3098E family of high-speed receivers. The MAX3098 variant specifically includes enhanced fault detection thresholds compared to the MAX3097. The 'B' suffix indicates a specific grade of fault detection sensitivity defined in the electrical characteristics tables.

FAQ

How is the delayed fault output time determined?

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

What fault conditions trigger the alarm outputs?

The alarms trigger for open-circuit conditions, short-circuit conditions, low differential voltage signals, and common-mode range violations.

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

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