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  
transceiver (5 drivers, 3 receivers) for fast modem  
applications.  
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.  
The device has  
a
proprietary low-dropout  
transmitter output stage providing true RS-232
