MAX203ECWP

Drivers, Receivers, Transceivers Overview

The MAX203ECWP is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers within a 20-SOIC surface-mount package. The device operates on a single +5V supply, utilizing integrated internal capacitors to eliminate the need for external charge-pump components. It supports data rates up to 120kbps with an operating temperature range of 0°C to +70°C. Electrical specifications include a typical supply current of 15mA, receiver input hysteresis of 500mV, and ±15kV ESD protection via the Human Body Model.

Drivers, Receivers, Transceivers Feature Summary

• Integrated internal capacitors eliminate the requirement for external charge-pump components.
• Provides high electrostatic discharge protection rated at ±15kV using the Human Body Model.
• Operates from a single +5V power supply through internal voltage conversion circuitry.

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

Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as specific suffixes may vary in regulatory adherence. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure storage conditions align with moisture sensitivity level requirements to prevent package damage during assembly.

Drivers, Receivers, Transceivers Selection Notes

Select this component when board space savings are critical due to the elimination of external capacitors. Choose this part for applications requiring robust ESD protection on RS-232 lines without additional protective circuitry. Verify that the 20-SOIC package footprint matches the PCB layout constraints. Ensure the system operates within the specified 0°C to +70°C temperature range for reliable performance.

Drivers, Receivers, Transceivers Part Context

The MAX203E belongs to the MAX202E–MAX213E family of RS-232 transceivers designed for single-supply operation. This family integrates charge-pump circuitry to generate the necessary positive and negative voltages from a single +5V source. The MAX203E specifically distinguishes itself by incorporating internal capacitors, reducing the bill of materials and simplifying the design process compared to variants requiring external components.
