MAX3212 is a low-power serial interface chip using Maxim's Auto-Shutdown mode. It has 3 RS-232 drivers and 5 RS-232 receivers, and works with a power supply of 2.7V to 3.6V. It is compatible with EIA/TIA-232E and V.28/V.24 standards and has a data transmission speed of 235kbps.
The MAX3212 is a low‑power RS‑232 line driver/receiver from Maxim. It provides three drivers and five receivers, operates from 2.7 V to 3.6 V, and maintains true RS‑232 voltage levels across the range. The device includes Maxim’s Auto‑Shutdown feature that reduces supply current to 1 µA when no valid signal is detected.
The transceiver is offered in 28‑pin SO and SSOP packages and guarantees a data rate of 235 kbps. Detailed electrical characteristics, timing specifications, and pin descriptions are provided for designers integrating the part into notebook, palmtop, and battery‑powered equipment.
