This document is the datasheet of MAX3238
The MAX3238 integrates five line drivers and three line receivers with a dual charge‑pump circuit, allowing operation from a single 3‑V to 5.5‑V supply. It meets TIA/EIA‑232‑F standards, supports data rates up to 250 kbit/s, and includes an always‑active non‑inverting output (ROUT1B) for ring‑indicator applications.
The device offers auto‑powerdown plus, which shuts off the charge pump and drivers after about 30 s of inactivity, reducing standby current to approximately 1 µA. It is available in DB (SSOP) and PW (TSSOP) packages, with ordering numbers such as MAX3238CDB and MAX3238CPW. The datasheet also contains mechanical dimensions, absolute‑maximum ratings, and TI’s standard warranty notice.
