DESCRIPTION
The ST3237E is a 3V to 5.5V powered EIA/
TIA-232 and V.28/V.24 communication interfaces
high
data-rate
capability
electrostatic discharge (ESD) protection at ±8KV
using IEC1000-4-2 contact discharge and ±15kV
using Human Body Model (HBM). The other pins
are protected with standard ESD protection at
±2kV using HBM method. The ST3237C is a
transceiver (5 drivers, 3 receivers) for fast modem
applications.
The
device
has
a
proprietary
transmitter output stage providing true RS-232
and
enhanced
low-dropout
performance from a 3V to 5.5V supply using a
dual charge pump. The device is guaranteed to
run at data rates of 250Kbps in the normal
operation mode and 1Mbps in the very high speed
operation mode while maintaining RS-232 output
levels.
