MAX3314E
±15kV ESD-Protected, 460kbps, 1µA, RS-232-Compatible Transceiver
Save Board Space with the ±5V, 1-Tx/1-Rx Transceiver
|
Status
Active: In Production.
Description
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.
