The device

Key Features

  • Wide supply voltage range from 2.3 V to 3.6 V.
  • Overvoltage switching on switch ports:.
  • 0 V to 5 V switching with VCC = 2.5 V.
  • 0 V to 5 V switching with VCC = 3.3 V.
  • 4 Ω (typical) ON resistance.
  • 3.5 pF (typical) OFF-state capacitance.
  • High bandwidth 0.5 GHz (maximum).
  • Low input/output capacitance minimizes loading and signal distortion.
  • Fast switching frequency fmax = 20 MHz (maximum).
  • Low power consumption.
