SP3232EUCT-L/TR

Drivers, Receivers, Transceivers Overview

The SP3232EUCT-L/TR is a MaxLinear RS-232 transceiver featuring two drivers and two receivers. It operates from a single 3.0V to 5.5V supply, utilizing an internal charge pump to generate ±5.5V levels. The device supports data rates up to 120kbps under full load (RL=3kΩ, CL=1000pF) and 235kbps with lighter loads. It includes enhanced ESD protection rated at ±15kV Human Body Model and ±15kV IEC61000-4-2 Air Discharge. The component is housed in a TSSOP-16 package and functions within a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated high-efficiency charge pump generates true RS-232 voltage levels from a single low-voltage power supply without requiring external high-voltage sources.
• Provides robust electrostatic discharge tolerance on all driver outputs and receiver inputs, ensuring reliability in sensitive environments.
• Features internal slew rate limiting to minimize electromagnetic interference while maintaining compatibility with standard PC-to-PC communication protocols.

Drivers, Receivers, Transceivers Applications

• Portable and handheld computing devices such as notebook or palmtop computers
• Battery-powered systems requiring efficient serial communication interfaces
• Mixed voltage systems interfacing TTL/CMOS logic with RS-232 standards

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'UCT' against official MaxLinear documentation to confirm exact packaging and temperature grade details. Ensure the ordering information matches the required TSSOP-16 configuration and lead-free status specified in the datasheet for this series.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a 2-driver, 2-receiver RS-232 interface is needed without shutdown functionality. Compare against the SP3222E if low-power shutdown modes are required. Confirm that the TSSOP-16 package dimensions fit the target PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SP3232E series, which provides true RS-232 performance from low-voltage supplies. It serves as a direct replacement for legacy RS-232 transceivers in modern portable electronics, offering improved power efficiency and ESD resilience compared to older generation components.

Drivers, Receivers, Transceivers Replacement Considerations

The SP3232EEA-L/TR and SP3232EEY-L/TR are confirmed substitutes within the same series offering identical electrical characteristics but differing in package type (SSOP-16 vs TSSOP-16). Verify pinout compatibility before substitution.
