? 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
