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 ±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
SSOP
SOP
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 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..
