  • Power supply: 5V ±10%
  • Rail to rail I/O
  • Internal hysteresis: 6 mV Typ.
  • Push-Pull CMOS output stage: ±16mA Max
  • Propagation delay: 29ns Typ. (with 20 mV overdrive)
  • Shutdown current consumption: 1 nA Typ. (25°C)
  • Static current consumption:
    • 600 μA Typ. (@ 25°C) 
    • 1.2 mA Typ. (@ 175°C) 
  • Maximum operating frequency: 25 MHz Typ.
  • Package: Plastic SOIC8 (5.0 x 6.0mm)
