MAX203EEWP

Drivers, Receivers, Transceivers Overview

The MAX203EEWP is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +5V supply and features integrated charge-pump circuitry, eliminating the need for external capacitors. The device includes two drivers and two receivers, supporting data rates up to 120kbps. It provides ±15kV ESD protection via the Human Body Model. The component is housed in a 20-pin SOIC package with an operating temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates external capacitor requirements
• High electrostatic discharge protection on all pins
• Single +5V power supply operation
• Full-duplex communication capability

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix EEWP confirms the extended industrial temperature range (-40°C to +85°C) and SOIC package type. Confirm RoHS compliance status as historical records indicate potential non-compliance for older batches. Check current production status as this family has faced discontinuation notices from the manufacturer.

Drivers, Receivers, Transceivers Selection Notes

Select this part when external charge-pump capacitors must be avoided to save board space. Ensure the application requires only two driver and receiver channels. Verify that the system voltage remains within the specified +5V tolerance. Consider alternative parts if shutdown mode functionality is required, as this variant lacks control pins.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX202E-MAX213E family of RS-232 transceivers. Unlike other members requiring external capacitors, the MAX203E integrates them internally. It shares pinout compatibility with similar 20-pin devices but differs in internal capacitor integration and lack of shutdown controls found in higher-end variants like the MAX213E.
