Dual bidirectional I2C-bus and SMBus voltage-level translator

2.

Features

I 2-bit bidirectional translator for SDA and SCL lines in mixed-mode I2C-bus applications

I Standard-mode, Fast-mode, and Fast-mode Plus I2C-bus and SMBus compatible

I Less than 1.5 ns maximum propagation delay to accommodate Standard-mode and

Fast-mode I2C-bus devices and multiple masters

I Allows voltage level translation between:

N 1.0 V Vref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias(ref)(2)

N 1.2 V Vref(1) and 1.8 V, 2.5 V, 3.3 V or 5 V Vbias(ref)(2)

N 1.8 V Vref(1) and 3.3 V or 5 V Vbias(ref)(2)

N 2.5 V Vref(1) and 5 V Vbias(ref)(2)

N 3.3 V Vref(1) and 5 V Vbias(ref)(2)

I Provides bidirectional voltage translation with no direction pin

I Low 3.5 Ω ON-state connection between input and output ports provides less signal

distortion

I Open-drain I2C-bus I/O ports (SCL1, SDA1, SCL2 and SDA2)

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

I High-impedance SCL1, SDA1, SCL2 and SDA2 pins for EN = LOW

I Lock-up free operation

I Flow through pinout for ease of printed-circuit board trace routing

I ESD protection exceeds 2000 V HBM per JESD22-A114, 200 V MM per

JESD22-A115, and 1000 V CDM per JESD22-C101

I Packages offered: SO8, TSSOP8, VSSOP8, XQFN8
