  • TCA9406: Any I2C level shift supports over 3.1MHz?

    Part Number: TCA9406 Other Parts Discussed in Thread: PCA9306 Hi Team, Customer is asking if TI has any I2C level shift that can support 3.1MHz clock freq? Thanks! Andrew

  • TCA9406: Relationship between VCCA and VCCB during power-on transient time

    Part Number: TCA9406 Hi Team, It is mentioned in the datasheet that VCCA must be less than or equal to VCCB (except during power-on transient time), do you have a number for the "power-on transient time"? In my application, VCCA will always be…

  • TCA9406: TCA9406 - 1V8 to 1V8 translation

    TI Thinks Resolved
    Part Number: TCA9406 Hi, I am using TCA9406 for level translation in multiple places in design. Unfortunately due to copy-paste error one of the them is also between two independent 1V8 domains, meaning that VCCB violates 2V3 requirement. The bus seems…

  • TCA9406: Use a TCA9406 with multiple I2C devices

    TI Thinks Resolved
    Part Number: TCA9406 Hi, I need to add a 1.8V slave to my design. After looking for an I2C level translator, TCA9406 seems to be a good candidate for the job however I'm little confuse whether it is able to upper the voltage from VCCA to VCCB or lower…
