1μA Supply Current, 1.8V to 4.25V-Powered  
RS-232 Transceiver with AutoShutdown  
MAX3218  
General Description  
Features  
The MAX3218 RS-232 transceiver is intended for bat-  
tery-powered EIA/TIA-232E and V.28/V.24 communica-  
tions interfaces that need two drivers and two receivers  
with minimum power consumption from a single low-  
voltage supply. It provides a wide +1.8V to +4.25V  
operating voltage range while maintaining true RS-232  
and EIA/TIA-562 voltage levels. The MAX3218 runs  
from two alkaline, NiCd, or NiMH cells without any form  
of voltage regulator. A guaranteed 120kbps data rate  
provides compatibility with popular software for com-  
municating with personal computers.  
BETTER THAN BIPOLAR!  
o 1µA Supply Current Using AutoShutdown  
o Operates Directly from Two Alkaline,  
NiCd or NiMH Cells  
o +1.8V to +4.25V Single-Supply Voltage Range  
o 120kbps Data Rate Guaranteed  
o Low-Cost Surface-Mount Components  
o Meets EIA/TIA-232E Specifications  
o Three-State Receiver Outputs  
o Flow-Through Pinout  
Supply current is reduced to 1µA with Maxim’s new  
AutoShutdown™ feature. When the MAX3218 does not  
sense a valid signal level on the 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 either RS-232 receiver input. As a result, the system  
saves power without changes to the existing software.  
Additionally, the MAX3218 can be forced into or out of  
shutdown, under logic control.  
o On-Board DC-DC Converters  
o 20-Pin SSOP and DIP Packages

While shut down, all receivers can remain active or can  
be disabled under logic control, permitting a system  
incorporating the CMOS MAX3218 to monitor external  
devices while in low-power shutdown. Three-state dri-  
vers are provided on both receiver outputs so that multi-  
ple receivers, generally of different interface standards,  
can be on the same bus. The MAX3218 is available in  
20-pin DIP and SSOP packages.
