8:More information

 

The MAX220–MAX249 family of line drivers/receivers is intended for all 

EIA/TIA-232E and V.28/V.24 communications interfaces, particularly applications where 

±12V is not available. 

 

    These parts are especially useful in battery-powered systems, 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 applications where printed circuit board space is critical.
