MAX202EESE+

Drivers, Receivers, Transceivers Overview

The MAX202EESE+ is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It integrates charge pump circuitry for single +5V supply operation, eliminating the need for external bipolar power sources. The device features two drivers and two receivers with data rates up to 120kbps. It operates within a voltage range of 4.5V to 5.5V and supports an extended temperature range of -40°C to +85°C. The component provides ±15kV ESD protection on transmitter outputs and receiver inputs. It is housed in a 16-pin Narrow SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Hand-held equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +85°C) compared to standard commercial grades. Confirm the 'SE' designation corresponds to the narrow SOIC package variant. Ensure RoHS compliance documentation matches 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 robust ESD protection for frequently connected serial ports. It is suitable for applications where space constraints prevent the use of dual-polarity power supplies. Compare against non-E versions if operating temperatures remain within the commercial range. Consider the 120kbps speed limit when evaluating high-speed communication requirements.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX202E-MAX213E family of RS-232 transceivers. These components share common architecture but vary in driver/receiver counts and shutdown capabilities. The MAX202E specifically provides a 2-driver, 2-receiver configuration. It serves as a foundational interface solution for legacy serial communication protocols in modern embedded systems.

Drivers, Receivers, Transceivers FAQ

Does the MAX202EESE+ include internal shutdown control?

No, the MAX202E does not feature internal shutdown or enable control pins. Only the MAX205E through MAX213E variants include these low-power management features.

What external components are required for operation?

Four external 0.1μF capacitors are required to support the integrated charge pump voltage converters. No other external components are necessary for basic functionality.

How does the E version differ from the standard MAX202?

The 'E' suffix denotes enhanced ESD protection rated at ±15kV HBM and an extended industrial temperature range (-40°C to +85°C), whereas standard versions typically offer lower ESD tolerance and commercial temperature ranges.
