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 is a +5 V powered RS‑232‑compatible transceiver with a low‑dropout output stage that delivers +3.7 V levels while driving 3 kΩ and 1000 pF at up to 460 kbps. It features a shutdown (SHDN) function that reduces supply current to 1 pA while keeping the receiver active.
The device is offered in 8‑pin SOT23, uMAX, and SO packages, with detailed pin descriptions, absolute maximum ratings, electrical and timing characteristics, and application notes for digital cameras, PDAs, GPS, POS terminals, and set‑top boxes.
