• 2-bit bidirectional translator for SDA and SCL lines in

  mixed-mode I2C-bus applications

• Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus

  and SMBus compatible

• Less than 1.5 ns maximum propagation delay to

  accommodate Standard mode and Fast mode I2C-bus

  devices and multiple masters

• Allows voltage level translation between:

  ◆ 0.9V VREF1 and 1.8 V,2.5 V,3.3 V or 5 V VREF2

  ◆ 1.2VVREF1 and1.8V,2.5V,3.3Vor5VVREF2

  ◆ 1.5 V VREF1 and2.5 V,3.3 V or 5 V VREF2

  ◆ 1.8 V VREF1 and3.3 Vor 5V VREF2

  ◆ 2.5 VVREF1 and 5 VVREF2

  ◆ 3.3 VVREF1 and 5 VVREF2

• Provides bidirectional voltage translation with no 

  direction pin

• Low 3.5 ohmON-state connection between input and

  output ports provides less signal distortion

• Open-drain I2C-bus I/O ports (SCL1, SDA1, SCI2 and

  SDA2)

• 5 V tolerant I2C-bus I/O ports to support mixed-mode

  signal operation

• High-impedance SCL1, SDA1, SCL2 and SDA2 pins for

  EN =LOW

• Lock-up free operation for isolation when EN = LOW

• Flow through pin out for ease of printed-circuit board

  trace routing

• ESD protection exceeds 4KV HBM per JESD22-Al14

• Package: TDFN2x3-8L,MSOP-8L,SOIC-8L
