MAX220–MAX249
+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.
The MAX225, MAX233, MAX235, and MAX245/MAX246/
MAX247 use no external components and are
recommended for applications where printed circuit
board space is critical.
The MAX220-MAX249 are offered in 26 different pack-
ages with temperatures from 0 to +70°C up to -55°C to
+125°C. See ordering information table at the end of the
data sheet for all package and temperature options.
Applications
