SP3223EUEA-L/TR

Drivers, Receivers, Transceivers Overview

The SP3223EUEA-L/TR is an intelligent RS-232 transceiver manufactured by MaxLinear, designed for high-speed serial communication in portable and handheld applications. It features two drivers and two receivers supporting full-duplex data transfer at rates up to 1 Mbps. The device operates on a single power supply ranging from +3.0V to +5.5V and includes a regulated charge pump to generate stable RS-232 voltage levels. Key electrical specifications include a maximum output current of 35 mA, a propagation delay of 0.15 µs, and an operating temperature range of 0°C to +70°C. The component is housed in a 20-pin SSOP package.

Drivers, Receivers, Transceivers Feature Summary

• Intelligent AUTO ON-LINE circuitry automatically wakes the device from microamp shutdown mode without external control signals.
• Regulated charge pump ensures stable RS-232 outputs regardless of variations in the VCC power supply voltage.
• High ESD protection ratings provide robustness against electrostatic discharge events during handling and operation.

Drivers, Receivers, Transceivers Applications

• Portable computers and laptops requiring high-speed serial connectivity
• Handheld devices and personal digital assistants (PDAs)
• Industrial equipment with RS-232 interface requirements

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix EA-L/TR against official MaxLinear documentation to confirm the exact package type and reel configuration. Ensure compatibility with the target PCB footprint for the 20-SSOP housing. Confirm moisture sensitivity level handling procedures are followed during assembly to prevent damage.

Drivers, Receivers, Transceivers Selection Notes

Select this model when a data rate of 1 Mbps is required, distinguishing it from the standard 120 kbps SP3223EE variants. Verify that the commercial temperature range (0°C to +70°C) meets the environmental constraints of the application. Check if the integrated shutdown feature aligns with the system's power management strategy.

Drivers, Receivers, Transceivers Part Context

This component belongs to the SP3223E series of intelligent RS-232 transceivers. The 'EU' designation within the part number indicates the high-speed variant capable of 1 Mbps operation, whereas other suffixes like 'EE' denote lower speed versions. The series is characterized by its ability to operate from a single low-voltage supply while maintaining true RS-232 performance standards.

Drivers, Receivers, Transceivers Replacement Considerations

SP3223EEA-L: Compatible pinout but limited to 120 kbps data rate. SP3223ECA-L: Commercial grade alternative with similar functionality but different packaging options. SP3223ECY-L: TSSOP-20 package variant with identical electrical characteristics to the EE series.
