MAX203EWP

Drivers, Receivers, Transceivers Overview

The MAX203EWP is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-pin Wide SO package. It operates on a single +5V supply with an operating temperature range of -40°C to +85°C. The device integrates two drivers and two receivers, supporting data rates up to 120kbps. Internal charge pump circuitry generates the required ±10V levels without external components, utilizing four integrated 0.1µF capacitors.

Drivers, Receivers, Transceivers Feature Summary

• Integrates internal charge pump circuitry for single-supply operation
• Eliminates need for bipolar ±12V power supply
• Includes built-in 0.1µF capacitors to save board space

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment
• Handheld equipment
• Portable diagnostics equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'E' indicates the extended industrial temperature range (-40°C to +85°C) and 'WP' denotes the 20-pin Wide SOIC package. Check for RoHS compliance status as older batches may not meet current environmental standards.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring full-duplex RS-232 communication with minimal external passive components. It is suitable for applications constrained by board space due to its integrated capacitor design. Ensure the system provides a stable +5V supply within the specified tolerance for optimal performance.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of RS-232 transceivers designed for single +5V operation. Unlike other variants that require external capacitors, the MAX203 specifically incorporates them internally. This integration simplifies the schematic and reduces the overall footprint compared to traditional RS-232 solutions requiring multiple discrete capacitors.
