SP3223EUEY-L/TR

Drivers, Receivers, Transceivers Overview

The SP3223EUEY-L/TR is an RS-232 interface integrated circuit manufactured by MaxLinear. It features two drivers and two receivers supporting full-duplex communication with a data rate of 235 kb/s. The device operates on a single power supply ranging from 3 V to 5.5 V, consuming 300 uA of quiescent current. It includes a shutdown mode for low-power applications. The component provides 15 kV ESD protection and functions within a temperature range of -40°C to +85°C. It is housed in a TSSOP-20 package suitable for surface mount technology.

Drivers, Receivers, Transceivers Feature Summary

• Intelligent charge pump design enables true RS-232 performance from a single low-voltage power supply.
• Integrated shutdown mode significantly reduces power consumption by disabling outputs and the charge pump.
• Enhanced electrostatic discharge protection ensures reliability in portable and handheld environments.

Drivers, Receivers, Transceivers Applications

• Portable computers and laptops
• Handheld devices and PDAs
• Battery-powered instrumentation

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 compliance. Ensure the ordering information matches the exact electrical specifications required for the target application before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-driver RS-232 transceiver is needed for space-constrained designs. The TSSOP-20 package offers a compact footprint compared to larger alternatives. Verify that the 235 kb/s data rate meets system requirements and that the 3 V to 5.5 V supply range aligns with the available power rails.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3223E series of intelligent RS-232 transceivers. The series is designed for portable applications requiring low power consumption and high ESD immunity. The 'UEY' designation typically indicates the TSSOP-20 package variant within this product family.

Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives within the same MaxLinear series or other manufacturers offering similar 2/2 driver/receiver configurations in TSSOP-20 packages. Verify equivalent voltage ranges and data rates before substitution.
