MAX202ECUE

Drivers, Receivers, Transceivers Overview

The MAX202ECUE is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates two drivers and two receivers within a single package, supporting data rates up to 120kbps under standard loading conditions. The device operates on a single +4.5V to +5.5V supply voltage and utilizes an internal charge pump circuitry to generate the required ±10V levels for RS-232 signaling, eliminating the need for external bipolar supplies. It features high electrostatic discharge (ESD) protection rated at ±15kV using the Human Body Model. The component is designed for commercial temperature ranges, specifically operating between 0°C and +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single-supply operation without requiring external bipolar power sources.
• High ESD protection capability of ±15kV ensures robustness against static discharges during handling and assembly.
• Internal receiver input thresholds are optimized to ensure logic high outputs when inputs are shorted to ground or left open.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low-power interface solutions
• Hand-held diagnostic tools and portable measurement devices
• Portable computers and notebook systems with frequent connection changes

Drivers, Receivers, Transceivers Procurement Notes

Verify that the specific part number suffix corresponds to the intended package type and temperature range. Confirm compliance with RoHS directives and REACH regulations as specified in the manufacturer's documentation. Ensure ordering details match the exact functional requirements regarding driver and receiver counts.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full-duplex RS-232 interface is required with integrated charge pumps. It is suitable for applications needing ±15kV ESD protection on I/O lines. Consider the commercial temperature range limits and the requirement for four external 0.1μF capacitors for the charge pump circuitry.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX202E-MAX213E family of RS-232 transceivers. It shares architectural similarities with other members like the MAX202EESE+ but differs in temperature rating and packaging. The 'C' suffix typically denotes the commercial temperature range, distinguishing it from industrial variants.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other members of the MAX202E family such as MAX202ESE+ or MAX202ECSE+, provided the package and temperature specifications align with the design requirements.

Drivers, Receivers, Transceivers FAQ

Does the MAX202ECUE require external capacitors for its charge pump?

Yes, the MAX202ECUE requires four external 0.1μF capacitors to support the internal charge pump circuitry for generating ±10V levels.

What is the ESD protection rating for the RS-232 inputs and outputs?

The device provides ±15kV ESD protection on the transmitter outputs and receiver inputs when tested using the Human Body Model.

Can unused driver inputs be left unconnected?

No, the MAX202ECUE does not have internal pull-up resistors on the transmitter inputs; therefore, unused driver inputs must be connected to a defined logic level.
