The MAX3314 is a ±5V powered EIA/TIA-232-compati-
ble 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-com-
patible ±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 sup-
ply 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.
19-1725; Rev 1a; 3/01
