Product Summary

The ST3232EBDR is a 3V powered EIA/TIA-232 and V.28/V.24 communication interfaces 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. ST3232EBDR 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. The ST3232EBDR has two receivers and two drivers. The device is guaranteed to run at data rates of 250Kbps while maintaining RS-232 output levels. Typical applications are Notebook, Subnotebook and Palmtop Computers, Battery Powered Equipment, Hand-Held Equipment, Peripherals and Printers.
