MAX3221/MAX3223/

MAX3243

+3V to +5.5V RS-232

Transceivers with AutoShutdown

General Description

Beneﬁts and Features

● Integrated Charge Pump Circuitry Simplifies Power

The MAX3221/MAX3223/MAX3243 achieve 1µA supply

current with Maxim’s revolutionary AutoShutdown™

feature. When the MAX3221/MAX3223/MAX3243 do not

sense a valid signal level on their receiver inputs, the on-

board power supply and drivers shut down. This occurs

if the RS-232 cable is disconnected or if the transmitters

of the connected peripheral are turned off. The system

turns on again when a valid level is applied to any RS-232

receiver input.

Requirements

• Eliminates the Need for a ±12 Supply

• Operation From a Single +3.3V or +5V Supply

● 1µA Supply Current in Shutdown Mode Saves Power

• AutoShutdown Feature is Enabled After No Activity

on Receiver Inputs for 30µs

• Software Control Option for Shutdown

The MAX3221/MAX3223/MAX3243 require only 0.1µF

capacitors in 3.3V operation, and can operate from input

voltages ranging from +3.0V to +5.5V.
