RS-232

Maxim's RS-232 solutions for PIN Pad Terminals have advanced features for the best signal integrity and most robust systems possible.
  • Enhanced ESD Protection
    • ±15kV, per Human Body Model
    • ±15kV, per Airgap Discharge IEC 1000-4-2
    • ±8kV, per Contact Discharge IEC 1000-4-2
  • True RS-232 Signal Levels with Single 3V or 5V Supplies
  • Integrated Charge Pumps Reduce Board Space and Design Complexity
  • Complete Serial-Port Transceiver (Three Drivers, Five Receivers)
