Product Summary
The ST3232EBTR is a 3V powered EIA/TIA-232 and V.28/V.24 communication interface with low power requirements, high data-rate capabilities and enhanced electrostatic discharge (ESD) protection to ±8kV using IEC1000-4-2 Contact Discharge and ±15kV using the Human Body Model. The ST3232EBTR has a proprietary low dropout transmitter output stage providing true RS-232 performance from 3 to 5V supplies witha a dual charge pump. The charge pump requires only four small 0.1µF standard external capacitors for operations from 3V supply.
