Analog Devices MAX3314E Product Info

• ESD Protection for RS-232 I/O Pins
  • ±15kV—Human Body Model
  • ±8kV—IEC 1000-4-2 Contact Discharge
  • ±15kV—IEC 1000-4-2 Air-Gap Discharge
• 1µA Low-Power Shutdown with Receiver Active
• 30µA Operating Supply Current
• 460kbps Guaranteed Data Rate
• 8-Pin SOT23 Package
• ±3.7V RS-232-Compatible Levels

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 3 kilohms and 1000pF at 460kbps. Both +5V and -5V must be supplied externally.

The MAX3314E has a active-low 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.
