The MAX3314E is a ±5V powered EIA/TIA-232-compatible interface with a single transmitter and a single 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 sup- ply 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 that includes one transmitter and one receiver in a flow‑through architecture. It offers robust ESD protection (±15 kV Human Body Model, ±8 kV Contact, ±15 kV Air‑Gap) and a low‑power shutdown mode that reduces supply current to 1 µA while keeping the receiver active.
Key specifications include a guaranteed 460 kbps data rate with 3 kΩ and 1000 pF load, minimum ±3.7 V output levels, and availability in 8‑pin SOT23, µMAX and SO packages. The device operates from +5 V and –5 V supplies and features a SHDN pin for power‑saving control. Applications span digital cameras, PDAs, GPS, telecommunications, set‑top boxes and other handheld equipment.
