SP3232EET-L

Drivers, Receivers, Transceivers Overview

The SP3232EET-L is a MaxLinear RS-232 transceiver featuring two drivers and two receivers. It operates from a single 3.0V to 5.5V supply, utilizing an internal charge pump to generate ±5.5V levels with only four 0.1µF external capacitors. The device supports data rates up to 120kbps under full load (RL=3kΩ, CL=1000pF) and achieves 235kbps in lighter loads. It provides enhanced ESD protection of ±15kV HBM and ±8kV IEC contact discharge. Operating temperature ranges from -40°C to +85°C. Supply current is typically 0.3mA at no load. Driver output short-circuit current reaches 35mA typical.

Drivers, Receivers, Transceivers Feature Summary

• Complies with true EIA/TIA-232-F standards using a single low-voltage power supply
• Integrates a high-efficiency proprietary charge pump requiring minimal external capacitance
• Provides robust electrostatic discharge tolerance across all driver and receiver pins
• Delivers reliable serial communication performance for portable and handheld applications

Drivers, Receivers, Transceivers Applications

• Portable and hand-held computing devices such as notebook or palmtop computers
• Battery-powered systems requiring efficient voltage translation without negative rails
• Mixed voltage environments interfacing 3.3V logic with standard RS-232 peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the ordering information table, as suffixes denote distinct packaging methods like tube or reel. Confirm that the lead-free designation aligns with environmental compliance requirements for the target assembly process. Ensure the operating temperature range matches the intended deployment environment specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-driver, dual-receiver interface is required without shutdown control functionality. The SP3232EET-L is suitable for designs needing industrial temperature stability (-40°C to +85°C). Compare against the SP3222E series if a low-power shutdown mode with active receivers is necessary instead.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3232E series within the broader SP3222E/SP3232E family. It shares core electrical characteristics with other variants but differs in physical packaging and thermal management capabilities. The 'L' suffix indicates lead-free construction compliant with environmental directives.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible alternatives include other SP3232E variants with different packages, such as SP3232EEA-L or SP3232EEN-L. Cross-brand replacements like MAX3232 require verification of charge pump capacitor values and pinout alignment.
