MAX3314E Datasheet, PDF (1/8 Pages) Maxim Integrated Products – ±15kV ESD-Protected, 460kbps, 1μA, RS-232-Compatible Transceiver

19-1696; Rev 1; 3/01
±15kV ESD-Protected, 460kbps, 1µA,
RS-232-Compatible Transceiver
General Description
The MAX3314E is a ±5V-powered EIA/TIA-232-compat-
ible 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 provid-
ing 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.
