Product Highlight

  • Data Rate: 400 kbps
  • ESD Voltage-Max: ±15 kV
  • Operating Temp Range: -40 to +85 °C
  • Supply Voltage: 3 to 5.5 V

The ST3241EBPR device consists of 3 drivers, 5 receivers and a dual charge-pump circuit. The device meets the requirements of EIA/TIA and V.28/V.24 communication standards providing high data rate capability and enhanced electrostatic discharge (ESD) protection. All transmitter outputs and receiver inputs are protected to ±8 kV using IEC 1000-4-2 contact discharge and ±15 kV using the human body model.

The receiver R2 is always active to implement a wake-up feature for serial port. The ST3241E has a proprietary low-dropout transmitter output stage enabling true RS-232 performance from a 3.0 V to 5.5 V supply with a dual charge pump. The device is guaranteed to run at data rates of 250 kbps while maintaining RS-232 output levels.
