Overview

The SN65C3232EDR is a dual-channel, low-power RS-232 line driver and receiver designed for high-speed serial communication up to 1Mbps. It operates over a wide supply voltage range of 3V to 5.5V and features robust ESD protection, including +/-15-kV Human-Body Model and IEC 61000-4-2 Air-gap discharge protection. With a typical supply current of only 0.3mA, it is well-suited for battery-powered and portable equipment requiring efficient asynchronous communication.

Why Choose This Part

This transceiver offers enhanced reliability with +/-15-kV ESD protection and high-speed performance capable of reaching 1Mbps data rates. Its 3V to 5.5V operating range ensures compatibility with both legacy 5V logic and modern 3.3V microcontrollers without needing level shifters.

Applications

Industrial Automation
Reliable serial communication between PLCs, sensors, and human-machine interfaces in electrically noisy environments.
Battery-Powered Handhelds
Low 300uA typical supply current extends operating life in portable diagnostic and data collection tools.
Networking Equipment
Provides a robust console port interface for switches, routers, and server management hardware.

Getting Started

To implement this part, place four 0.1-uF charge-pump capacitors as close to the IC pins as possible to ensure stable internal voltage doubling and inversion. For prototyping, use a standard SOIC-16 to DIP adapter and ensure the RX/TX lines are correctly crossed relative to the DTE or DCE equipment being interfaced.
