The MAX3238E and MAX3248E are 3 V‑powered RS‑232 transceivers that integrate five drivers and three receivers. They feature Maxim’s AutoShutdown Plus technology, which reduces supply current to 10 nA when no valid signal transitions are detected, and provide enhanced ESD protection on all I/O pins.
The devices operate from a single +3.0 V to +5.5 V supply, guarantee a 250 kbps data rate, and support low‑level logic thresholds (MAX3248E) for 1.8 V systems. Detailed electrical characteristics, pin descriptions, and application notes are included for designers of cell‑phone data cables, modems, and other peripheral equipment.
