Key Features

  • Simple impedance isolating buffer for 2-wire buses
  • 4 mA maximum static open-drain pull-down capability supports a wide range of bus standards
  • Works with I2C-bus (Standard-mode, Fast-mode), SMBus (standard and high power mode), and PMBus
  • Fast switching times allow operation in excess of 1 MHz
  • Enable allows bus segments to be disconnected
  • Hysteresis on inputs provides noise immunity
  • Operating voltages from 2.7 V to 5.5 V
