MAX232 - Communication Interface Driver Introduction

Introduction:

+5V powered, multi-channel RS-232 driver/receiver

MAX232

description:

The MAX220–MAX249 family of line drivers/receivers are designed for EIA/TIA-232E and V.28/V.24 communication interfaces, especially those that do not provide ±12V power.

These devices are ideal for battery-powered systems because their low-power shutdown mode reduces power consumption to less than 5μW. The MAX225, MAX233, MAX235, and MAX245/MAX246/MAX247 require no external components and are recommended for applications with limited printed circuit board space.

application:

Laptop

Low power modem

Interface conversion

Battery powered RS-232 system

Multi-point RS-232 network

Key characteristics

For low voltage, integrated ESD applications

MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E: +3.0V to +5.5V, Low Power, Up to 1Mbps, True RS-232 Transceiver with Four 0.1μF External Capacitors (MAX3246E Available in UCSPTM Package)

For low cost applications MAX221E: ±15kV ESD-protected, +5V, 1μA, single RS-232 transceiver with AutoShutdown
