SCPS221C – OCTOBER 2010 – REVISED DECEMBER 2014 TCA9406 2-Bit Bidirectional 1-MHz, I2C Bus and SMBus Voltage-Level Translator With
8-kV HBM ESD
1 Features 3 Description The TCA9406 is a 2-bit bidirectional I2C and SMBus
voltage-level translator with an output enable (OE)
input. It is operational from 1.65 V to 3.6 V on the Aside, referenced toVCCA, and from 2.3 V to 5.5 V on
the B-side, referenced to VCCB. This allows the device
to interface between lower and higher logic signal
levels at any of the typical 1.8-V, 2.5-V, 3.3-V, and 5V supply rails. 1 2-Bit Bidirectional Translator for SDA and SCL
