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.
The MAX220‑MAX249 series are +5 V‑powered, multichannel RS‑232 drivers and receivers designed for applications where a +12 V supply is unavailable. They feature ultra‑low shutdown power (under 5 µW) and are suitable for portable computers, modems, and battery‑powered RS‑232 networks.
The document lists absolute maximum ratings, electrical characteristics, typical operating curves, and ordering information for each part number in the family, including package types, temperature ranges, and pin‑outs.
