+3V to +5.5V RS-232  
MAX3221/MAX3223/MAX3243  
General Description  
Transceivers with AutoShutdown  
Benefits and Features  
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.  
• Integrated Charge Pump Circuitry Simplifies Power  
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.  
Ordering Information  
A proprietary, high-efficiency, dual charge-pump power  
supply and a low-dropout transmitter combine to deliv-  
er true RS-232 performance from a single +3.0V to  
+5.5V supply.
