Product Summary

The ST3237EBPR is a transceiver. The ST3237EBPR 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 ST3237EBPR is a transceiver (5 drivers, 3 receivers) for fast modem applications. The ST3237EBPR 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.
