Overview

The TRS3232EIDBR is a dual-channel RS-232 line driver and receiver designed for high-performance serial communication between 3V and 5.5V systems. It features integrated ESD protection on the RS-232 bus pins and utilizes a low-power charge pump circuit to maintain standard-compliant signal levels while using only four external 0.1uF capacitors.

Why Choose This Part

This transceiver offers a wide supply voltage range of 3V to 5.5V, ensuring compatibility with both legacy 5V logic and modern 3.3V microcontrollers. It provides enhanced ESD protection on bus-facing pins and maintains a 250kbps data rate across its full -40C to 85C operating temperature range.

Applications

Industrial Computing
Reliable serial interface for industrial PCs and embedded controllers requiring robust ESD protection.
Battery-Powered Systems
Ideal for hand-held equipment and notebooks due to its low 0.3mA typical supply current at 3.3V or 5V.
Networking Hardware
Serves as a console port or management interface for wired networking and data center equipment.
Point-of-Sale Terminals
Connects peripherals like barcode scanners and receipt printers in retail environments.

Getting Started

To implement this device, place four 0.1uF charge-pump capacitors near the IC pins as specified in the datasheet to ensure stable voltage doubling and inversion. Connect the logic-side T1IN/T2IN and R1OUT/R2OUT pins directly to your MCU's UART, ensuring the Vcc supply matches your logic levels for proper signal integrity.
