TCA9406 Datasheet - Texas Instruments

TCA9406 2-Bit Bidirectional 1-MHz I2C Bus and SMBus Voltage-Level Translator

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 highe.

TCA9406 Features

* 1 2-Bit Bidirectional Translator for SDA and SCL Lines in I2C Applications

* Provides Bidirectional Voltage Translation With No Direction Pin

* High-Impedance Output SCL_A, SDA_A, SCL_B, SDA_B Pins When OE = Low or VCC = 0 V

* Internal 10-kΩ Pullup Resistor on All SD
