SP3232EEA-L/TR

Overview

The SP3232EEA-L/TR is a dual-channel RS-232 transceiver designed for portable or battery-powered systems operating from a 3.0V to 5.5V supply. It features an efficient charge pump requiring only four 0.1uF external capacitors to generate the necessary RS-232 voltage levels while maintaining a low typical shutdown current of 10uA.

Why Choose This Part

This transceiver is a high-performance, drop-in replacement for industry-standard 3232 devices, offering enhanced ESD protection and a compact 16-pin SSOP footprint. It maintains full RS-232 data rates while supporting low-voltage logic levels, eliminating the need for multiple power rails in modern digital systems.

Applications

Getting Started

To integrate this part, place four 0.1uF surface-mount ceramic capacitors close to the V+, V-, and charge pump pins as specified in the datasheet. Ensure the TTL/CMOS side is connected to your microcontroller UART pins while the RS-232 side interfaces with the D-Sub connector or external link.
