The ST3237E is a 3 V to 5.5 V powered EIA/TIA-232 and V.28/V.24 communication interfaces high data-rate capability and enhanced electrostatic discharge (ESD) protection at ±8 kV using IEC1000-4-2 contact discharge and ±15 kV using Human Body Model (HBM). The other pins are protected with standard ESD protection at ±2 kV 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 performance from a 3 V to 5.5 V supply using a dual charge pump. The device is guaranteed to run at data rates of 250 kbps in the normal operation mode and 1 Mbps in the very high speed operation mode while maintaining RS-232 output levels.
The ST3237EB is an RS-232 transceiver designed for high data-rate applications with enhanced electrostatic discharge (ESD) protection. It features a proprietary low-dropout transmitter output stage that provides true RS-232 performance from a single 3 V to 5.5 V supply using a dual charge pump. The device supports guaranteed data rates of up to 1 Mbps in very high speed operation mode and includes +15 kV protection for I/O pins under the human body model.
