ST3237E Datasheet | STMicroelectronics

DESCRIPTION The ST3237E is a 3V to 5.5V powered EIA/ TIA-232 and V.28/V.24 munication interfaces high data-rate capability and enhanced electrostatic discharge (ESD) protection at ±8KV using IEC1000-4-2 contact discharge and ±15k V using Human Body Model (HBM). The other pins are protected with standard ESD protection at ±2k V 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 ORDERING CODES Type ST3237ECD ST3237EBD ST3237ECDR ST3237EBDR ST3237ECPR ST3237EBPR ST3237ECTR (- ) ST3237EBTR Temperature Range 0 to 70 °C -40 to 85 °C 0 to 70 °C -40 to 85 °C 0 to 70 °C -40 to 85 °C 0 to 70 °C -40 to 85 °C Package performance from a 3V to 5.5V supply using a dual charge pump.
