MAX211ECAI

Drivers, Receivers, Transceivers Overview

The MAX211ECAI+ is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It integrates four drivers and five receivers with an internal dual charge pump for +5V operation using only four 0.1µF external capacitors. The device supports data rates up to 120kbps and features ±15kV HBM ESD protection on all pins. It operates within a commercial temperature range of 0°C to +70°C and is housed in a 28-pin SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four drivers and five receivers with internal charge pump circuitry for single +5V supply operation
• Provides ±15kV Human Body Model ESD protection on all pins including serial port connection pins
• Includes shutdown (SHDN) and enable (EN) control functions to minimize power consumption

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CAI' against official documentation to confirm the exact package type and temperature rating. Confirm RoHS compliance status through manufacturer datasheets or authorized distributors. Ensure the ordering code matches the required 28-pin SSOP form factor and commercial grade specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring multiple RS-232 channels with high ESD tolerance. It is suitable for applications needing low standby current via shutdown mode. Verify that the 0.1µF capacitor requirement fits the board space constraints compared to devices requiring larger capacitors.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX202E–MAX213E family of RS-232 transceivers designed for harsh environments. The 'E' designation indicates enhanced ESD protection capabilities. The MAX211 variant specifically offers a combination of four drivers and five receivers, making it distinct from other family members with different channel counts.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX211EEAI+ for extended temperature ranges. Other variants like the MAX213E offer additional awake-in-shutdown receivers but differ in control logic polarity.
