概述

Description

The MAX3221ECDBR is a low-power, dual RS-232 transceiver designed for communication between a microcontroller and serial devices. It operates with a supply voltage from 3.0V to 5.5V and provides reliable data transmission over a distance of up to 15 meters at speeds of 120 kbps. The device features a built-in charge pump that generates the necessary voltage levels for RS-232 signaling, allowing it to achieve true RS-232 voltage levels (±5V) from a single supply.
Key features include low power consumption, a small package size (SOIC-16), and high data integrity with built-in protection against ESD. The MAX3221ECDBR is suitable for portable applications, such as handheld devices, and industrial equipment. It is ideal for applications requiring asynchronous serial communication, such as modems, printers, and data acquisition systems. Its robust performance and ease of integration make it a popular choice for designers implementing RS-232 interfaces in their electronic systems.

Features

The MAX3221ECDBR is a high-performance RS-232 transceiver designed for communication between microcontrollers and peripheral devices. Key features include:
1. Voltage Range: Operates with a single supply voltage of 3.0V to 5.5V.
2. Data Rate: Supports data rates up to 250 kbps.
3. Transmitter and Receiver: Includes a transmitter and a receiver with 1µA low-power shutdown mode.
4. Input/Output Levels: Converts TTL/CMOS logic levels to RS-232 voltage levels and vice versa.
5. Integrated Capacitors: The device features internal charge pumps and requires only one external capacitor for operation, simplifying design.
6. Temperature Range: Rated for operation from -40°C to +85°C.
7. Pin Configuration: Available in a 16-pin TSSOP package, saving PCB space.
8. Protection: Offers short-circuit protection and thermal shutdown.
Overall, the MAX3221ECDBR is ideal for compact, power-sensitive applications needing reliable serial communication.
