MAX3222EEUP+G1Z

Overview

The MAX3222EEUP+G1Z is a true RS-232 transceiver manufactured by Analog Devices Inc./Maxim Integrated, housed in a 20-pin TSSOP package. It operates on a single +3.0V to +5.5V supply and features two drivers and two receivers for full-duplex communication. The device supports data rates up to 250kbps with ±5V output swings. It incorporates an internal dual charge pump requiring only four 0.1µF capacitors. Key electrical parameters include a typical supply current of 1mA, a shutdown current down to 1µA, and receiver propagation delay of 0.15µs. It provides enhanced ESD protection rated at ±15kV (Human Body Model) and ±8kV (IEC Contact Discharge).

Feature Summary

• Integrated dual charge pump enables true RS-232 performance from a single low-voltage supply.
• Enhanced electrostatic discharge protection safeguards transmitter outputs and receiver inputs against high-voltage static events.
• Dedicated shutdown control pin reduces power consumption significantly while maintaining receiver activity monitoring capabilities.

Applications

• Battery-powered portable equipment
• Cell phone and smartphone data cables
• Notebook and subnotebook computers

Procurement Notes

Verify the specific suffix G1Z against the manufacturer's official documentation to confirm packaging configuration and compliance status. Ensure the component source is authorized to guarantee authenticity. Cross-reference the part number with the latest datasheet revision to confirm availability and any potential obsolescence notices prior to procurement.

Selection Notes

Select this component when designing systems requiring compatibility with industry-standard MAX242/MAX232 interfaces but operating at lower voltages. It is suitable for applications needing reduced power consumption through shutdown modes. Verify that the required data rate does not exceed 250kbps and that the system voltage falls within the specified 3.0V to 5.5V range.

Part Context

This device belongs to the MAX3222E family of RS-232 transceivers designed for low-power, single-supply applications. It is functionally compatible with older MAX232 devices but offers improved ESD protection and lower power consumption. The EE designation indicates an extended temperature range of -40°C to +85°C, suitable for industrial environments.

Replacement Considerations

The MAX3222ECUP+ serves as a commercial grade alternative with a 0°C to +70°C temperature range. For higher speed requirements, the MAX3237E offers MegaBaud operation up to 1Mbps. Direct pin-compatible replacements should be verified against the specific package type and temperature rating requirements.
