MAX203ECPP

Drivers, Receivers, Transceivers Overview

The MAX203ECPP is a full-duplex RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers within a 20-pin Plastic DIP package. The device operates on a single +5V supply, utilizing integrated internal charge-pump capacitors to generate the required ±10V levels without external components. It supports data rates up to 120kbps and includes high ±15kV ESD protection on all RS-232 inputs and outputs. The component is rated for an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated internal charge-pump capacitors eliminate the need for external components
• High electrostatic discharge protection on RS-232 I/O pins
• Single +5V power supply operation with internal voltage conversion
• Full-duplex communication capability with TTL/CMOS compatible logic levels

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Hand-held diagnostic tools
• Portable instrumentation systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CPP' against official manufacturer documentation to confirm the 20-pin Plastic DIP package configuration. Confirm that the 'E' designation aligns with the required ±15kV ESD protection specifications. Ensure the commercial temperature range (0°C to +70°C) meets the operational environmental requirements of the target system before procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a full-duplex RS-232 interface is required in a space-constrained design. The integrated capacitors reduce board space compared to devices requiring external charge-pump components. Verify that the 120kbps maximum data rate satisfies the application's throughput needs and that the 20-pin DIP package fits the available footprint constraints.

Drivers, Receivers, Transceivers Part Context

The MAX203ECPP belongs to the MAX202E–MAX213E family of RS-232 transceivers. This family shares common architecture features such as single-supply operation and ESD protection. The MAX203 variant specifically distinguishes itself by integrating the charge-pump capacitors internally, simplifying the external circuit design compared to variants like the MAX202E which require four external capacitors.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the MAX203EEWP and MAX203CWP. These alternatives share the same functional core but differ in package type (SOIC vs. DIP) or compliance status. Verify pin compatibility and thermal characteristics when substituting.
