MAX3386E 3.0V, ±15kV ESD-Protected RS-232 Transceivers For PDAs And Cell Phones

The MAX3386E 3V-powered EIA/TIA-232 and V.28/V.24 is a Communications Interface with low power requirements, high data-rate capabilities, and enhanced electrostatic discharge (ESD) protection. The MAX3386E has two receivers and three transmitters. All RS-232 inputs and outputs are protected to 25kV using the IEC 1000-4-2 Air-Gap Discharge method, 8kV using the IEC 1000-4-2 Contact Discharge method, and 15kV using the Human Body Model.
A proprietary low-dropout transmitter output stage enables true RS-232 performance from a +3.0V to +5.5V supply with a dual Charge Pump The Charge Pump requires only four small 0.1F capacitors for operation from a +3.3V supply. The MAX3386E is capable of running at data rates up to 250kbps while maintaining RS-232 compliant output levels.
The MAX3386E has a unique VL pin that allows interoperation in mixed-logic voltage systems. Both input and output Logic levels are pin programmable through the VL pin. The MAX3386E is available in a space-saving TSSOP package.
