MAX203CWP

Drivers, Receivers, Transceivers Overview

The MAX203CWP is a +5V-powered, multichannel RS-232 transceiver featuring integrated charge pump circuitry for single-supply operation. It contains two drivers and two receivers, supporting full-duplex communication at data rates exceeding 120kbps under EIA/TIA-232E loading conditions. The device operates within a supply voltage range of 4.75V to 5.25V and consumes typically 8mA of operating current. It utilizes a 20-pin Wide SOIC package and functions reliably across an industrial temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates the need for external bipolar power supplies
• Internal capacitors reduce board space requirements
• TTL/CMOS compatible inputs and outputs

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CWP' corresponds to the 20-pin Wide SOIC package and the commercial temperature grade (0°C to +70°C). Confirm RoHS compliance status with the manufacturer or authorized distributor before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when minimizing external passive components is critical due to limited PCB area. Ensure the application requires only two driver/receiver channels and operates strictly on a single +5V supply without shutdown functionality needs.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX200-MAX209 family of RS-232 transceivers designed for single-supply applications. The MAX203 variant specifically integrates internal capacitors, distinguishing it from models requiring external components for charge pump operation.
