Package / Case
16-SOIC (0.300", 7.5mm Width)
Lead Free Status / RoHS Status
Lead free / RoHS Compliant
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,
MAX233, MAX235, and MAX245/MAX246/MAX247 use
no external components and are recommended for appli-
cations where printed circuit board space is critical.
