MAX202EESE

Drivers, Receivers, Transceivers Overview

The MAX202EESE+ is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates two drivers and two receivers within a 16-pin SOIC package. The device operates on a single +4.5V to +5.5V supply, utilizing an internal charge pump to generate the required ±10V levels for RS-232 signaling. It supports data rates up to 120kbps with a typical supply current of 15mA at +25°C. The component provides ±15kV ESD protection via the Human Body Model and functions reliably across an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables operation from a single +5V power supply without requiring external bipolar voltage sources.
• High electrostatic discharge (ESD) robustness with ±15kV Human Body Model protection on all RS-232 inputs and outputs.
• Receiver inputs feature guaranteed logic thresholds that ensure compatibility with both TTL and CMOS logic families.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Hand-held equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' confirms the industrial temperature grade (-40°C to +85°C) and enhanced ESD protection compared to commercial variants. Confirm the 'SE' designation corresponds to the narrow SOIC-16 package. Ensure RoHS compliance markings align with current manufacturing standards. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and traceability.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring dual-channel RS-232 communication under harsh environmental conditions. The integrated charge pump simplifies board layout by eliminating external inductors or dual supplies. Verify that the 120kbps maximum data rate meets application requirements. Consider the 16-pin footprint constraints against available PCB real estate. Evaluate the need for shutdown functionality if present in alternative family members.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX202E-MAX213E family of RS-232 transceivers designed for rugged environments. The 'E' suffix denotes extended temperature performance and enhanced ESD protection features. The MAX202E specifically provides a 2-driver, 2-receiver configuration. This family shares architectural similarities with the MAX232E but differs in capacitor requirements and pinout configurations.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the MAX202CSE+ for commercial temperature applications and the MAX232EESE+ for similar interface needs with different capacitor specifications. Verify pin compatibility and electrical characteristics before substitution.

Drivers, Receivers, Transceivers FAQ

What is the maximum data rate supported by the MAX202EESE+?

The device supports data rates up to 120kbps when loaded according to EIA/TIA-232E specifications.

Does the MAX202EESE+ include a shutdown mode?

No, the standard MAX202E does not include a shutdown control pin. Shutdown functionality is available in other family members such as the MAX205E, MAX206E, MAX211E, MAX213E, and MAX241E.

What type of capacitors are required for the charge pump?

The MAX202EESE+ requires four external 0.1μF capacitors for the charge pump circuit. Ceramic dielectrics are suggested for these components.
