MAX208ECNG

Drivers, Receivers, Transceivers Overview

The MAX208ECNG is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It features four drivers and four receivers operating at data rates up to 120kbps. The device utilizes an integrated charge pump to generate ±10V from a single +5V supply (4.5V to 5.5V), eliminating the need for external bipolar supplies. It provides ±15kV ESD protection on driver outputs and receiver inputs per the Human Body Model. The EC suffix indicates an industrial temperature range of 0°C to +70°C. The component is housed in a 24-pin SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry enables operation from a single +5V supply without requiring external bipolar voltage sources.
• High electrostatic discharge robustness with ±15kV Human Body Model protection on all RS-232 I/O pins.
• Full compliance with EIA/TIA-232E and CCITT V.28 specifications for signal levels and timing.
• CMOS/TTL compatible input thresholds allow direct interfacing with standard logic families.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring low power consumption
• Hand-held diagnostic tools
• Portable communication devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm pinout compatibility and electrical characteristics. Confirm that the package type matches the design requirements. Check for RoHS compliance status as defined in the latest datasheet revision. Ensure the temperature grade aligns with the intended operational environment constraints.

Drivers, Receivers, Transceivers Selection Notes

Select this component when four independent transmit and receive channels are required within a compact surface-mount footprint. The integrated charge pump simplifies board layout by removing the need for dual-rail power supplies. Verify that the maximum data rate requirement does not exceed 120kbps under the specific load capacitance conditions. Consider the 0°C to +70°C temperature range suitability for the target application environment.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers designed for single-supply applications. The family shares common architecture including integrated charge pumps and ESD protection structures. Variations within the family differ primarily in the number of drivers/receivers and the presence of shutdown control pins. The MAX208E specifically offers a balanced 4x4 configuration.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional replacements within the same family include other MAX208 variants such as MAX208EEWG+ or MAX208EAG+T, provided the package style and temperature range meet the design constraints. Cross-manufacturer equivalents like the ADM208 series may require verification of pinout compatibility and electrical parameter alignment.
