  • 5Ω switches connect inputs to outputs
  • High signal passing bandwidth (-3dB BW is 815MHz)
  • Beyond Rail-to-Rail switching
  • 5V I/O tolerant with 3.3V supply
  • 3.3V supply voltage operation
  • Hot insertion capable
  • Industrial operating temperature: -40ºC to +85ºC
  • ESD protection
    • 8kV per JESD22 test spec (HBM)
    • +/-4kV per IEC61000-4-2 spec (contact)
  • Latch-up performance >250mA per JESD17
  • Packaging (Pb-free & Green available):
    • 16-pin 150-mil wide plastic TSSOP (L)
