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 鹵 8 kV using IEC1000-4-2 Contact

Discharge and 鹵 15 kV using the Human Body

Model. 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 碌F 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.
