SP3220EUEA-L/TR

Drivers, Receivers, Transceivers Overview

The SP3220EUEA-L/TR is a single-driver, single-receiver RS-232 transceiver manufactured by MaxLinear. It operates within a supply voltage range of 3 V to 5.5 V and supports full-duplex communication with a data rate of 120 kb/s. The device features a low quiescent current of 300 uA and includes a shutdown mode for power reduction. It provides 15 kV ESD protection and operates across a temperature range of -40°C to +85°C. Packaged in a TSSOP-16 format, it delivers 35 mA output current with a propagation delay of 0.15 us.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a regulated charge pump to generate true RS-232 voltages from a single low-voltage supply.
• Includes a shutdown pin that disables drivers and the charge pump to minimize power consumption.
• Provides enhanced electrostatic discharge protection exceeding ±15kV on all pins.

Drivers, Receivers, Transceivers Applications

• Portable computing devices such as laptops and notebooks
• Handheld instruments and personal digital assistants
• Industrial control systems requiring low-power serial communication

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'L/TR' against the manufacturer's official documentation to confirm tape-and-reel packaging and lead-free status. Ensure the ordering information matches the exact TSSOP-16 package variant required for the design. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement specifications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single driver and receiver are sufficient for the interface requirements. It is suitable for designs constrained by space due to the compact TSSOP-16 package. Consider this part if the application demands low standby current via the shutdown feature while maintaining standard RS-232 signal levels over a wide temperature range.

Drivers, Receivers, Transceivers Part Context

This component belongs to the SP3220E series of intelligent RS-232 transceivers. The series is designed to replace traditional dual-supply solutions by operating from a single 3V to 5.5V source. The 'EU' designation typically indicates the TSSOP-16 package configuration within the product family.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other single-driver RS-232 transceivers with similar voltage ranges and packages, such as the MAX3222 or ST3222. Verify pin compatibility and electrical parameters like drive strength and ESD ratings before substitution.
