SP3232EUCN-L

Drivers, Receivers, Transceivers Overview

The MaxLinear SP3232EUCN-L is a dual-driver, dual-receiver RS-232 transceiver designed for portable applications. It operates from a single 3.0V to 5.5V supply and utilizes an internal charge pump to generate ±5.5V levels. The device supports data rates up to 235kbps under full load conditions. It features enhanced ESD protection rated at ±15kV for Human Body Model and IEC61000-4-2 Air Discharge testing. The component is housed in a 16-pin NSOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high-efficiency charge pump requiring only 0.1µF external capacitors
• Enhanced electrostatic discharge tolerance exceeding ±15kV across multiple test methods
• Full compliance with EIA/TIA-232-F standards using a single power supply
• Internal receiver pull-down resistors ensure defined logic states when inputs are unconnected

Drivers, Receivers, Transceivers Applications

• Portable and hand-held computing devices such as notebooks and palmtops
• Battery-powered systems requiring low standby current consumption
• Mixed voltage environments interfacing 3.3V or 5.0V logic with RS-232 peripherals

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm the exact package type and temperature range. Ordering codes often dictate mechanical dimensions and thermal characteristics. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring true RS-232 performance without external negative voltage generation. The device is suitable for systems operating between 3.0V and 5.5V. Note that unlike the SP3222E variant, this model lacks a shutdown pin, meaning it does not support active low-power sleep modes.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3232E series of line transceivers manufactured by MaxLinear. The series is engineered to replace legacy RS-232 drivers in modern low-voltage digital systems. It provides a compact solution for serial communication interfaces in space-constrained electronic assemblies.

Drivers, Receivers, Transceivers Replacement Considerations

SP3232EEN-L: Identical electrical specifications but packaged in NSOIC-16 instead of UCN. SP3232EEY-L: Equivalent performance metrics utilizing a TSSOP-16 package format.
