SP211ECA-L

Drivers, Receivers, Transceivers Overview

The MaxLinear SP211ECA-L/TR is an RS-232 transceiver featuring four drivers and five receivers. It operates on a single +5V supply with a voltage range of 4.5V to 5.5V. The device supports data rates up to 120 kb/s and includes internal charge pumps requiring only four 0.1μF capacitors. It offers full-duplex communication in an SSOP-28 package. Key electrical parameters include a maximum output current of 25 mA, typical static power consumption of 20 mA, and ESD protection ratings of ±15 kV. The component functions within an operating temperature range of 0°C to +70°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuit eliminates the need for external positive and negative voltage supplies
• High electrostatic discharge (ESD) protection on driver outputs and receiver inputs
• Low-power shutdown mode significantly reduces active current consumption
• Receiver input hysteresis ensures clean signal reception for slow-changing waveforms

Drivers, Receivers, Transceivers Applications

• RS-232 serial communication interfaces
• V.28 standard compliant systems
• Space-constrained electronic designs
• PC remote access applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L' against the manufacturer's official documentation to confirm the commercial temperature grade and pinout compatibility. Ensure the ordering code matches the required tape-and-reel packaging format. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single +5V supply is available and external high-voltage generation is undesirable. The SP211ECA-L provides a direct replacement for legacy industry-standard devices while offering enhanced ESD robustness. Consider the 120 kb/s speed limit and SSOP-28 footprint constraints during the initial hardware architecture phase.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MaxLinear SP211E series of enhanced RS-232 transceivers. The series is designed to be pin-compatible with previous generations and competitive industry standards. The 'E' designation indicates enhanced features such as improved ESD tolerance and lower power consumption compared to earlier iterations.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include the SP211EEA-L/TR and SP211EET-L/TR. These variants share the same functional core but differ in package type or manufacturing lot specifications. Verify pinout alignment before substitution.
