Product overview

Description

The ST3232E is a 3 V 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 ± 8 kV using IEC1000-4-2 contact discharge and ± 15 kV using the human body model. The ST3232E has a proprietary low-dropout transmitter output stage providing true RS-232 performance from 3 to 5 V supplies with a dual charge pump. The charge pump requires only four small 0.1 μF standard external capacitors for operations from 3 V supply.

The ST3232E has two receivers and two drivers. The device is guaranteed to run at data rates of 250 kbps while maintaining RS-232 output levels.
