SP3222EBEA-L/TR

Drivers, Receivers, Transceivers Overview

The SP3222EBEA-L/TR is a true +3V to +5.5V RS-232 transceiver manufactured by MaxLinear, Inc., designed for portable and handheld applications such as laptops and PDAs. It features two drivers and two receivers with full-duplex communication capabilities. The device operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 120 kbps. It includes a low-power shutdown mode that reduces supply current to less than 1 μA. The component provides enhanced ESD protection exceeding ±15 kV according to human body model and IEC1000-4-2 air discharge standards.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high-efficiency charge pump requiring only a 0.1 μF capacitor at 3.3 V operation
• Low-power shutdown mode disables drivers and charge pump for minimal standby current
• Enhanced electrostatic discharge tolerance for robust signal integrity in portable environments

Drivers, Receivers, Transceivers Applications

• Laptop computers
• Handheld personal digital assistants (PDAs)
• Portable industrial equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the datasheet, as suffixes indicate different physical footprints. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering suffix matches the exact pin configuration needed for your PCB layout design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a single-supply RS-232 solution is required for battery-powered devices. It is suitable for designs needing low quiescent current and high ESD immunity. Verify that the 120 kbps data rate meets system requirements and that the TSSOP-16 package fits the available board space constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3222E/3232E series of RS-232 transceivers from MaxLinear. The series is characterized by its ability to operate from a single 3V to 5.5V supply while delivering true RS-232 performance. It is widely used in mobile computing applications where power efficiency and compact packaging are critical design factors.

Drivers, Receivers, Transceivers Replacement Considerations

SP3222EEA-L/TR offers equivalent functionality in a 20-SSOP package. ADM3222ARUZ is a comparable alternative from Analog Devices. Verify pin compatibility and electrical specifications before substitution.
