232CPE
19-4323; Rev 15; 1/06
+5V-Powered, Multichannel RS-232
Drivers/Receivers
General Description
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 ±12V 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,
www.DataSheeMt4UA.Xco2m33, MAX235, and MAX245/MAX246/MAX247 use
no external components and are recommended for appli-
cations where printed circuit board space is critical.

Note 1: For the MAX220, V+ and V- can have a maximum magnitude of 7V, but their absolute difference cannot exceed 13V.
Note 2: Input voltage measured with TOUT in high-impedance state, SHDN or VCC = 0V.
Note 3: Maximum reflow temperature for the MAX233A is +225°C.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
