  TCA9406: Maximum operating junction temperature.

  TI Thinks Resolved

  Part Number: TCA9406 Hello! Do you have a maximum operating junction temperature for this device? I do not have estimated power dissipation values for this part yet, and want to set my upper limit based on your direction.

  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...

  TCA9406: Power Cycle

  Part Number: TCA9406 Hi Team, My customer has a question on the TCA9406. If they manually power cycle this device, would it cause any issues with other I2C devices on the same bus? Thanks, Mitchell

  RE: TCA9406: offset in B-side?

  Hi Anne, No, TCA9406 does not implement a voltage offset on either side. This is more common among "buffer" devices that re-drive the I2C signals. Instead, TCA9406 uses a switch-based approach that merely passes low levels through rather than...

  RE: TCA9406: Use a TCA9406 with multiple I2C devices

  Yes, that's fine since the 1.8V side has internal 10k pull up resistors. They do get turned off if the OE is low but it seems this won't be a concern since it's tied directly to VccA. -Bobby
