The MAX218 RS-232 transceiver is intended for battery-  
powered EIA/TIA-232E and V.28/V.24 communications  
interfaces that need two drivers and two receivers with  
minimum power consumption. It provides a wide +1.8V  
to +4.25V operating voltage range while maintaining  
true RS-232 a nd EIA/TIA-562 volta g e le ve ls . The  
MAX218 runs from two alkaline, NiCd, or NiMH cells  
without any form of voltage regulator.  
BETTER THAN BIPOLAR!  
Operates Directly from Two Alkaline, NiCd,  
or NiMH Cells  
+1.8V to +4.25V Supply Voltage Range  
120kbps Data Rate  
Low-Cost Surface-Mount Components  
Meets EIA/TIA-232E Specifications  
1µA Low-Power Shutdown Mode  
Both Receivers Active During Low-Power Shutdown  
Three-State Receiver Outputs  
A shutdown mode reduces current consumption to  
1µA, extending battery life in portable systems. While  
shut down, all receivers can remain active or can be  
disabled under logic control, permitting a system incor-  
p ora ting the CMOS MAX218 to monitor e xte rna l  
devices while in low-power shutdown mode.  
Flow-Through Pinout  
A guaranteed 120kbps data rate provides compatibility  
with popular software for communicating with personal  
computers. Three-state drivers are provided on all  
receiver outputs so that multiple receivers, generally of  
different interface standards, can be wire-ORed at the  
UART. The MAX218 is available in 20-pin DIP, SO, and  
SSOP packages.
