The MAX3314E is a ±5V powered EIA/TIA-232 compatible interface. It has one transmitter and one receiver in a flow-through architecture. The transmitter output and the receiver input are protected to ±15kV using IEC 1000-4-2 Air-Gap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge, and ±15kV using the Human Body Model. 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 must be supplied externally. The MAX3314E has a SHDN function that reduces supply current to 1µA. The transmitter is disabled and put into tristate while the receiver remains active. The MAX3314E is available in 8-pin µMAX, SOT23, and SO packages.
The MAX3314E is a +5 V‑powered RS‑232‑compatible transceiver with a flow‑through architecture that includes one transmitter and one receiver. It offers ESD protection up to +15 kV and a low‑dropout output stage that delivers a minimum +3.7 V RS‑232 level while driving 3 kΩ and 1000 pF loads at 460 kbps.
The device is supplied in 8‑pin SOT23‑8, UMAX, and SO packages and features a shutdown function that reduces supply current to 1 pA while keeping the receiver active. Detailed pin descriptions, electrical characteristics, timing data, and package dimensions are provided for designers.
