The ST3237E is a 3V to 5.5V powered EIA/TIA-232 and V.28/V.24 communication interface with 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. 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.
The ST3237E is a low-power RS-232 transceiver designed for operation with a supply voltage ranging from 3V to 5.5V. It features enhanced electrostatic discharge (ESD) protection, rated at +15kV for the Human Body Model and +8kV for IEC 1000-4-2 contact discharge. The device utilizes a proprietary low-dropout transmitter output stage with a dual charge pump to achieve true RS-232 performance levels from the low-voltage supply.
