MAX207ECWG+

Drivers, Receivers, Transceivers Overview

The MAX207ECWG+ is a single-supply RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a +5V supply and includes an integrated charge pump to generate the required ±10V levels, eliminating the need for external bipolar supplies. The device features five drivers and three receivers, supporting data rates up to 120kbps. It provides high electrostatic discharge (ESD) protection of ±15kV via the Human Body Model on all driver outputs and receiver inputs. The component is housed in a 24-pin SOIC package and is rated for operation within a temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables single +5V supply operation without requiring external bipolar voltage sources.
• High ±15kV ESD HBM protection on all RS-232 driver outputs and receiver inputs ensures reliability in harsh environments.
• Compliant with EIA/TIA-232E and CCITT V.28 specifications for reliable serial communication.
• Five independent drivers and three receivers provide flexible interface configurations.

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CWG+' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Confirm that the 24-pin SOIC package matches the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Drivers, Receivers, Transceivers Selection Notes

Select this part when a single +5V supply is available and multiple transmit lines are needed. The MAX207E requires four external 0.1μF capacitors for the charge pump. Compare against the MAX206E or MAX208E if different driver/receiver counts are required. Verify that the 120kbps data rate is sufficient for the application.

Drivers, Receivers, Transceivers Part Context

The MAX207E belongs to the MAX202E–MAX213E family of RS-232 transceivers. This series is designed for robust communication in noisy environments. The 'E' designation indicates enhanced ESD protection compared to standard versions. The device simplifies board design by integrating the voltage conversion necessary for RS-232 signaling.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the MAX206E and MAX208E from the same family. These parts share similar electrical characteristics but differ in the number of drivers and receivers. Verify pin-to-pin compatibility before substitution.
