Key Features

  • Dual, bidirectional unity gain isolating buffer
  • Hot insertion logic prevents data and clock bus corruption for live backplane applications
  • Pre-charge minimizes data corruption on live insertion
  • Supports I2>C-bus (Standard-mode and Fast-mode), SMBus (standard and high power modes) and PMBus
  • Open-collector ready output (RDY)
  • Fast switching times allow operation in excess of 1 MHz
  • Enable (EN) allows bus segments to be disconnected
  • Low current standby mode when not enabled
  • High-impedance ports when IC unpowered
  • 6 mA (static) pull-down capability
  • Low noise susceptibility
  • Supports the connection of several buffers in series
  • Level shift bus voltages from 1.8 V to 10 V
