+5V-Powered, Multichannel RS-232  
Drivers/Receivers  
General Description  
____________________________Features  
The MAX220–MAX249 family of line drivers/receivers is  
intended for all EIA/TIA-232E and V.28/V.24 communica-  
tions interfaces, particularly applications where ±±2V is  
not available.  
These parts are especially useful in battery-powered sys-  
tems, since their low-power shutdown mode reduces  
power dissipation to less than 5µW. The MAX225,  
MAX233, MAX235, and MAX245/MAX246/MAX247 use  
no external components and are recommended for appli-  
cations where printed circuit board space is critical.  
Superior to Bipolar  
o Operate from Single +5V Power Supply  
(+5V and +12V—MAX231/MAX239)  
o Low-Power Receive Mode in Shutdown  
(MAX223/MAX242)  
o Meet All EIA/TIA-232E and V.28 Specifications  
o Multiple Drivers and Receivers  
o 3-State Driver and Receiver Outputs  
o Open-Line Detection (MAX243)
