MAX202EESE+T

Drivers, Receivers, Transceivers Overview

The MAX202EESE+T is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +4.5V to +5.5V supply and includes an integrated charge pump circuitry for voltage conversion, eliminating the need for external bipolar supplies. The device features two drivers and two receivers with a maximum data rate of 120kbps. It provides ±15kV ESD protection via the Human Body Model and meets IEC1000-4-2 standards. The component is housed in a 16-pin Narrow SO package and supports an operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables operation from a single +5V supply without requiring external bipolar power sources.
• High electrostatic discharge (ESD) protection rated at ±15kV Human Body Model on all RS-232 inputs and outputs.
• Compliance with EIA/TIA-232E and CCITT V.28 specifications for driver output levels and receiver input thresholds.
• Robust design suitable for harsh environments or applications involving frequent connection changes.

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 extended industrial temperature range (-40°C to +85°C) compared to commercial variants. Confirm the 'T' suffix indicates tape-and-reel packaging if reel handling is required for assembly. Ensure the ordering information matches the exact pinout and electrical characteristics defined in the official datasheet to avoid functional mismatches.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust ESD protection and simplified power management using a single +5V source. It is appropriate for interfaces where data rates do not exceed 120kbps. Consider the 16-pin Narrow SO package dimensions for PCB layout constraints. Verify that external 0.1μF capacitors are available for the charge pump circuit as specified in the typical operating circuits.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E-MAX213E family of RS-232 transceivers. These devices share common architecture including integrated charge pumps and high ESD protection. The MAX202E specifically offers two drivers and two receivers, distinguishing it from other family members like the MAX232E which shares similar pinouts but may differ in capacitor requirements or internal configurations.
