The MAX3314 is a ±5V powered EIA/TIA-232-compatible interface. It has one transmitter and one receiver in a flow-through architecture. The transmitter has a low-dropout output stage providing minimum RS-232-compatible ±3.7V output levels while driving 3kΩ and 1000pf at 460kbps. Both +5V and -5V are supplied externally. The MAX3314 has a SHDN function that reduces supply current to 1µA. The transmitter is disabled and put into 3-state mode while the receiver remains active. The MAX3314 is available in 8-pin SOT23, µMAX and SO packages.
The MAX3314 provides a single transmitter and receiver in a flow‑through architecture, delivering RS‑232‑compatible ±3.7 V output levels while driving 3 kΩ and 1000 pF loads at up to 460 kbps. It operates from external ±5 V supplies and includes a shutdown (SHDN) function that reduces supply current to 1 µA while keeping the receiver active.
The device is offered in 8‑pin SOT‑23, µMAX and SO packages and features low operating currents (30 µA typical in shutdown) and a wide temperature range (‑40 °C to +85 °C for some packages). Detailed electrical, timing, and package specifications are provided for designers.
