Key Features

  • Dual, bidirectional unity gain buffer
  • Fast switching times allow operation in excess of 1 MHz
  • Supports I2C-bus (Standard-mode and Fast-mode), SMBus (standard and high power mode), PMBus and IPMB
  • Enable allows bus segments to be disconnected
  • Low standby current when not enabled
  • Application/removal of power to IC will not interfere with other bus activity
  • 6 mA (static) pull-down capability supports a wide range of bus standards
  • Low noise susceptibility
  • Low input-output offset voltage
  • Threshold and offset parameters allow the connection of several devices in series
  • Bus levels independent of supply voltage
  • Operating voltages from 2.7 V to 5.5 V
  • Wide range of bus voltages from 1.8 V to 10 V
  • Level shifting between different bus voltages
  • Achieves superior response times without the need for rise time accelerators
  • ESD protection exceeds 2 kV HBM per JESD22-A114 and 500 V CDM per JESD22-C101
  • Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100 mA
