DESCRIPTION

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

TIA-232 and V.28/V.24 communication interfaces

high data-rate capability and enhanced

electrostatic discharge (ESD) protection at 鹵8KV

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

using Human Body Model (HBM). The other pins

are protected with standard ESD protection at

鹵2kV 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
