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 family provides +5 V‑powered multichannel RS‑232 line drivers and receivers designed for low‑power, battery‑operated systems where +12 V is unavailable. Applications include portable computers, low‑power modems, interface translation, and multidrop RS‑232 networks.
The datasheet lists absolute maximum ratings, detailed electrical characteristics, and a wide range of package options (DIP, SO, SSOP, QFP, etc.). Ordering information, selection tables, and typical operating curves help designers choose the appropriate part and configure it for low‑power shutdown, high‑speed data rates up to 1 Mbps, and various temperature ranges.
