SP3222EBET-L

Drivers, Receivers, Transceivers Overview

The SP3222EBET-L is a MaxLinear RS-232 transceiver featuring two drivers and two receivers. It operates on a single 3V to 5.5V supply with a typical quiescent current of 300µA. The device supports data rates up to 235kb/s and includes a shutdown mode reducing current below 1µA. It utilizes an internal charge pump requiring only a 0.1µF capacitor for ±10V generation. ESD protection exceeds ±15kV per human model and IEC 1000-4-2 air discharge standards. The component is housed in an 18-pin SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high-efficiency charge pump minimizes external component count by requiring only a single small capacitor.
• Low power consumption design suitable for battery-operated portable devices, featuring a dedicated shutdown mode.
• Robust electrostatic discharge tolerance ensures reliability in harsh environments without additional protection circuitry.

Drivers, Receivers, Transceivers Applications

• Portable computers and laptops
• Handheld terminals and PDAs
• Industrial control systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix ET against official MaxLinear documentation to confirm pinout compatibility and package dimensions. Confirm availability status as distribution listings may indicate end-of-life or limited stock conditions. Ensure moisture sensitivity level handling procedures are followed during assembly to prevent package damage.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-driver RS-232 interface is required for space-constrained designs. Compare the 235kb/s speed limit against higher-speed alternatives if data throughput requirements exceed this threshold. Verify that the 18-pin SOIC footprint matches the target PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3222E series, designed for low-power RS-232 communication. It serves as a direct replacement for legacy MAXIM MAX3222 devices in many applications. The series emphasizes miniaturization through reduced external capacitance requirements while maintaining full EIA/TIA-232-F compliance.
