SP211EA-L

Drivers, Receivers, Transceivers Overview

The SP211EA-L is a low-power, high-ESD RS-232 transceiver manufactured by MaxLinear. It features four drivers and five receivers, supporting data rates up to 120Kbps with a single +5V supply. The device operates within a voltage range of 4.5V to 5.5V and includes an internal charge pump requiring only four 0.1μF external capacitors. Static current is typically 3mA, reducing to 1μA in shutdown mode. It offers ±15kV ESD protection on driver outputs and receiver inputs, functioning reliably between -40°C and +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump eliminates need for external dual-voltage power supplies
• High electrostatic discharge tolerance protects sensitive serial interfaces
• Low power shutdown mode extends battery life in portable applications

Drivers, Receivers, Transceivers Applications

• Space-constrained embedded systems requiring RS-232 connectivity
• Industrial equipment with harsh electrical environments
• Portable devices utilizing single-supply operation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with SSOP-28 or SOIC-28 footprints as specified in the datasheet. Confirm RoHS compliance status through the latest component certification documents provided by MaxLinear before integration into production designs.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for single-supply +5V operation with minimal external capacitance requirements. The integrated charge pump simplifies board layout compared to traditional RS-232 transceivers. Consider the shutdown mode functionality if power management is critical for the target application environment.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP200 series of enhanced RS-232 transceivers from MaxLinear. It maintains pin compatibility with previous generations like the SP211 and industry-standard competitors. The series is designed to replace older discrete solutions while offering improved ESD robustness and lower power consumption for modern serial communication needs.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the SP211E and SP213E from the same family. These parts share pinout compatibility and core functionality. Verify specific receiver counts and wake-up capabilities when substituting, as the SP213E includes additional always-on receivers not present in the SP211EA.
