SP3203EEY-L

Drivers, Receivers, Transceivers Overview

The SP3203EEY-L is an RS-232 transceiver manufactured by MaxLinear, Inc., designed for portable and handheld applications. It features a 3-driver and 2-receiver architecture operating from a single +3.0V to +5.5V power supply. The device incorporates a high-efficiency internal charge pump requiring only 0.1μF capacitors at 3.3V operation. It meets EIA/TIA-232-F standards and ensures interoperability with EIA/TIA-562 down to +2.7V sources. Key electrical parameters include a minimum data rate of 250Kbps under load, ±5kV Human Body Model ESD protection, and ±8kV IEC61000-4-2 contact discharge tolerance.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a logic selector function (VL) to set TTL input/output levels for mixed logic systems
• Utilizes a regulated charge pump to yield stable RS-232 outputs regardless of VCC variations
• Provides enhanced electrostatic discharge protection specifications for robust operation

Drivers, Receivers, Transceivers Applications

• Palmtops
• Cell phone data cables
• Personal Digital Assistants (PDAs)

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin carefully, as Exar Corporation was the original designer and MaxLinear acquired Exar's interface business. Confirm that the specific part number suffix corresponds to the correct package type and RoHS compliance status required for your assembly process. Cross-reference the datasheet version to ensure alignment with current regulatory standards and pinout configurations before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a three-transmitter configuration is required alongside two receivers in a compact form factor. It is suitable for designs needing a logic level selector to interface between different voltage domains. Ensure the application supports the 0.1μF external capacitor requirement for the charge pump. Verify that the ±5kV HBM ESD rating meets the environmental safety requirements of the target portable device.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SP3203E series of intelligent RS-232 transceivers. It shares architectural similarities with other low-voltage RS-232 solutions but distinguishes itself through the inclusion of a logic selector pin. The series is optimized for battery-powered devices where power efficiency and minimal external component count are critical design constraints.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements may include other 3-driver/2-receiver RS-232 transceivers from the same family or competitors offering similar pinouts. Verify compatibility regarding the logic selector functionality and charge pump capacitor requirements. Check for equivalent ESD protection levels and operating voltage ranges to ensure seamless integration without circuit redesign.
