MAX3250EAI+T Description

Short technical summary and product information.

The MAX3250EAI+T is a versatile RS-232 transceiver designed by Analog Devices (Maxim Integrated) for robust communication in noisy environments. It provides ±50V isolation, protecting against high common-mode voltages and ground loops, making it suitable for industrial control, point-of-sale equipment, and telecom applications.

 

This transceiver supports a guaranteed data rate of 250kbps while maintaining RS-232 output levels. It operates from a wide supply voltage range of 3.0V to 5.5V on the logic side. The device features two drivers and two receivers, offering full-duplex communication.

 

A key feature is the FAULT open-drain output, which signals excessive isolated-side voltage conditions, allowing for system protection. The MAX3250EAI+T is available in a space-saving 28-pin SSOP package, ideal for applications where board space is limited. Its shutdown mode allows multiple interfaces to share the same UART, with high-impedance transmitter and receiver outputs.

 

Designed for reliability, this transceiver meets EIA/TIA-232 specifications down to 3.0V. It is a low-cost replacement for opto-isolated transceivers, simplifying EMI design with its inductorless/transformerless architecture.
