SP3232 vs MAX3232: A Comprehensive Comparison of RS-232 Transceivers The SP3232E family had a unique edge: it

The SP3232+ is a high-performance, 2-driver/2-receiver RS-232 transceiver IC manufactured by Exar Corporation (now part of MaxLinear). It operates at a low power consumption of 1 µA, making it suitable for battery-powered devices and power-sensitive applications. The SP3232+ features a wide operating voltage range of 3V to 5.5V, allowing it to interface with various microcontrollers and logic systems. SP3232 vs MAX3232: A Comprehensive Comparison of RS-232

Both chips are fully interchangeable on a PCB. Order samples of each. Run the same ESD gun on your prototype. The results will speak louder than any datasheet.

Both operate from 3.0V to 5.5V , allowing them to work in both legacy 5V systems and modern 3.3V projects.
