MAX3314E 19-1696 Rev 1 3/01 15kV ESD-Protected, 460kbps, 1A, RS-232-Compatible Transceiver General Description Features The MAX3314E is a 5V-powered EIA/TIA-232-compat- ESD Protection for RS-232 I/O Pins ible interface. It has one transmitter and one receiver in 15kVHuman Body Model a flow-through architecture. The transmitter output and 8kVIEC 1000-4-2 Contact Discharge the receiver input are protected to 15kV using IEC 15kVIEC 1000-4-2 Air-Gap Discharge 1000-4-2 Air-Gap Discharge, 8kV using IEC 1000-4-2 Contact Discharge, and 15kV using the Human Body 1A Low-Power Shutdown with Receiver Active Model. 30A Operating Supply Current The transmitter has a low-dropout output stage provid- 460kbps Guaranteed Data Rate ing minimum RS-232-compatible 3.7V output levels while driving 3k and 1000pF at 460kbps. Both +5V 8-Pin SOT23 Package and -5V must be supplied externally. 3.7V RS-232-Compatible Levels The MAX3314E has a SHDN function that reduces sup- ply current to 1A. The transmitter is disabled and put into tristate while the receiver remains active. The MAX3314E is available in 8-pin MAX, SOT23, and Ordering Information SO packages. PART TEMP.
