SP3238EEA-L

Drivers, Receivers, Transceivers Overview

The SP3238EEA-L is an intelligent RS-232 transceiver manufactured by MaxLinear, designed for full-duplex communication. It operates within a supply voltage range of +3.0V to +5.5V and supports data rates up to 250 kb/s. The device integrates five drivers and three receivers in a single package. It features a regulated charge pump that ensures stable RS-232 outputs regardless of VCC variations. The component includes ESD protection rated at 15 kV on I/O and logic pins. It utilizes SSOP-28 packaging and functions across a temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Intelligent AUTO ON-LINE circuitry automatically wakes the device from microamp shutdown mode without external control signals.
• Regulated charge pump architecture maintains stable RS-232 output voltages despite fluctuations in the power supply.
• High electrostatic discharge tolerance protects sensitive I/O and logic pins against environmental static events.

Drivers, Receivers, Transceivers Applications

• Industrial equipment requiring robust serial communication interfaces
• Portable computing devices such as laptops and handheld terminals
• Communication systems utilizing multiple RS-232 channels

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L' indicates lead-free compliance and confirm the 'EA' designation matches the required SSOP-28 package dimensions. Cross-reference the manufacturer datasheet to ensure the pinout aligns with the target design, as MaxLinear acquired Exar's portfolio and legacy part numbers may have subtle revision differences. Confirm RoHS status through official documentation before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a high channel count is necessary, specifically configurations requiring five drivers and three receivers. It is suitable for applications needing low standby current due to the automatic wake-up feature. Ensure the system operates within the specified 3V to 5.5V range and requires 250kbps throughput. Verify that the SSOP-28 footprint fits the PCB layout constraints compared to smaller packages like TSSOP or SOIC.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SP3238E series of intelligent RS-232 transceivers. It shares functional similarities with the MAX3238 but is produced under the MaxLinear brand following industry consolidation. The series is characterized by its ability to operate from a single low-voltage supply while generating the higher voltages required for RS-232 signaling standards.

Drivers, Receivers, Transceivers Replacement Considerations

The Analog Devices / Maxim Integrated MAX3238EEAI+ is a confirmed public substitute with identical electrical specifications and pinout compatibility. Both parts offer five drivers, three receivers, and 15kV ESD protection in an SSOP-28 package.
