SP3203EEY-L/TR

Drivers, Receivers, Transceivers Overview

The SP3203EEY-L/TR is a MaxLinear RS-232 transceiver featuring a 3-driver and 2-receiver architecture in a TSSOP-16 package. It operates from a single +3.0V to +5.5V supply, utilizing an internal charge pump requiring only 0.1µF capacitors at 3.3V. The device supports full-duplex communication with a minimum data rate of 250kbps under load. It includes a logic selector function (VL) for mixed logic systems and provides ±15kV ESD protection per human model standards. Operating temperatures range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a high-efficiency internal charge pump for stable RS-232 outputs from a single low-voltage supply.
• Includes a logic selector function to set TTL input/output levels for compatibility with mixed logic systems.
• Provides enhanced electrostatic discharge protection exceeding ±15kV human model and ±15kV IEC air discharge specifications.

Drivers, Receivers, Transceivers Applications

• Portable handheld devices such as palmtops and PDAs
• Cell phone data cables
• Mixed logic system interfaces requiring voltage translation

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official MaxLinear documentation to confirm pinout and electrical characteristics. Ensure the component source matches the manufacturer's authorized distribution channels to guarantee authenticity. Cross-reference the date code and lot number with current production status records before integration into final assembly processes.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a three-transmitter interface is required alongside two receivers in a compact surface-mount form factor. The integrated charge pump eliminates external inductors, simplifying PCB layout for battery-operated portable equipment. Verify that the operating voltage range aligns with the system's power supply rails and that the logic selector meets the target interface voltage requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3203E series of intelligent RS-232 transceivers designed for low-power portable applications. It shares architectural similarities with other MaxLinear SP32xxE devices but is distinct due to its specific 3-driver/2-receiver configuration and logic selector feature. The series is optimized for compliance with EIA/TIA-232-F standards while maintaining low standby currents.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SP3203EEY-L without the tape-and-reel suffix if tube packaging is acceptable. Other compatible variants within the SP3203E family may offer different package options or temperature grades. Verify functional equivalence regarding the logic selector and ESD ratings before swapping components.

Drivers, Receivers, Transceivers FAQ

What is the purpose of the VL pin on the SP3203EEY-L/TR?
