Product Introduction

Overview

The ADM232LAR-REEL, produced by Analog Devices Inc., is a 5 V-powered CMOS RS-232 driver/receiver integrated circuit. This component is part of the ADM2xx family and is designed to meet all EIA-232-E and V.28 specifications. It is particularly useful in applications where a single 5 V supply is available, and it does not require the traditional ±12 V supplies needed for RS-232 interfaces. The ADM232LAR-REEL is packaged in a 16-lead SOIC (Small Outline Integrated Circuit) and is suitable for a wide range of communication interfaces.

Key Features

  • Single 5 V power supply with on-board DC-DC converters to generate the required ±10 V for RS-232 output.
  • Meets all EIA-232-E and V.28 specifications.
  • Low power shutdown mode available in some models, reducing power dissipation to less than 5 µW.
  • No external components required for the ADM233L model, making it ideal for space-critical applications.
  • Internal 400 kΩ pull-up resistors on TTL/CMOS inputs and internal 5 kΩ pull-down resistors on RS-232 inputs.
  • Latch-up free operation.

Applications

  • Computers and peripherals.
  • Modems and printers.
  • Instruments and industrial equipment.
  • Battery-powered devices, benefiting from the low power shutdown mode.
  • Any application requiring EIA-232-E and V.28 compliant RS-232 interfaces with a single 5 V supply.
