Product Introduction

Overview

The MAX232BEAWE+ is an integrated circuit produced by Analog Devices Inc./Maxim Integrated, designed to convert signals between TIA-232 (RS-232) serial ports and TTL-compatible digital logic circuits. This dual driver/receiver IC is particularly useful in systems where ±12V power is not available, as it operates from a single 5V power supply. The MAX232BEAWE+ includes a capacitive voltage generator that supplies the necessary TIA/EIA-232-F voltage levels using external capacitors.

Key Features

  • Meets or exceeds TIA/EIA-232-F and ITU recommendation V.28 specifications.
  • Operates from a single 5V power supply with 1µF charge-pump capacitors (can also use 0.1µF capacitors for the MAX232A version).
  • Includes two drivers and two receivers.
  • Supports data rates up to 120kbps (up to 200kbps for the MAX232A version).
  • Low supply current: 8mA typical.
  • ESD protection exceeds JESD 22 – 2000V Human-body model (A114-A), with an upgrade to 15kV HBM available in the MAX202 device.
  • Converts TIA/EIA-232-F inputs to 5V TTL/CMOS levels and vice versa.

Applications

  • TIA/EIA-232-F interfaces.
  • Battery-powered systems.
  • Terminals and modems.
  • Computers and portable computers.
  • Low-power RS-232 systems and multidrop RS-232 networks.
