Description

The ST3237E is a 3 V to 5.5 V powered EIA/TIA-

232 and V.28/V.24 communication interfaces high

data-rate capability and enhanced electrostatic

discharge (ESD) protection at ±8 kV using

IEC1000-4-2 contact discharge and ±15 kV using

Human Body Model (HBM). The other pins are

protected with standard ESD protection at ±2 kV

using HBM method. The ST3237C is a

transceiver (5 drivers, 3 receivers) for fast modem

applications.

The device has a proprietary low-dropout

transmitter output stage providing true RS-232

performance from a 3 V to 5.5 V supply using a

dual charge pump. The device is guaranteed to

run at data rates of 250 kbps in the normal

operation mode and 1 Mbps in the very high

speed operation mode while maintaining RS-232

output levels.
