  • [FAQ] TUSB1044: How to configure a PD controller to configure TUSB1044 and support virtual HPD?

    Part Number: TUSB1044 When using a PD controller to configure a TUSB1044 (Type-C Linear Redriver) over I2C it is best to follow the scheme below for programming the PD in this regard. This scheme also includes support for applications in need of a "virtual…

  • [FAQ] definition of signal conditioner(redriver/repeater/retimer..)

    Dear experts, I want to understand the signal conditioner definition. would you explain what is difference between redriver and repeater and retimer ? Thanks, JH.

  • [FAQ] TUSB320LAI: Which pins on TUSB320LAI are non fail safe and are there any special considerations for these pins?

    Part Number: TUSB320LAI Other Parts Discussed in Thread: TUSB320HAI When using TUSB320LAI or TUSB320HAI are there any non fail safe pins? Which pins are non fail safe and what special considerations do I need to take into account when designing a Type…

  • [FAQ] What is the difference between an I2C device with the family name PCA and TCA?

    Other Parts Discussed in Thread: PCA9306 TI's I2C portfolio consists of devices with the family prefix of PCA and TCA (exception to PCF and P82 families). What are the differences and similarities between the two prefixes?

  • [FAQ] Can I2C IO expanders be used in an open drain configuration?

    Other Parts Discussed in Thread: TCA6507 TI's I2C IO expander portfolio is made up of mostly Push-Pull CMOS output structures. Questions about using these devices as open drain instead of push pull has occasionally popped up, so can TI's IO expanders…

  • [FAQ] TDP142: How do I debug the issue of a monitor having no display?

    Part Number: TDP142 I have a DP monitor that does not display, how do I debug this issue?

  • [FAQ] The datasheet for this LIN transceiver states it is compliant with LIN 2.0, 2.1, and 2.2A. Is it also compliant with LIN 1.3?

    Yes, it is. The changes from LIN 1.3 to LIN 2.0 and above are purely LIN protocol changes. The physical layer transceiver definition was not affected directly or through the protocol changes. For more information on the changes to the LIN specification…

  • [FAQ] CAN 5V and 3.3V CAN transceiver operate on the same bus together?

    Yes, they can. 3.3V CAN transceivers are designed to have their recessive level, dominant and recessive thresholds such that they will correctly transmit and receive messages from either a 5V or a 3.3V CAN transceiver. Within the 3.3V CAN transceiver…

  • [FAQ] My MCU uses 3.3V as the logic supply, do I need a 3.3V CAN transceiver?

    Unless you are working with a 3.3V CAN bus, you do not need a 3.3V CAN transceiver. There is a difference between 3.3V CAN transceivers and CAN transceivers with the ability to accept 3.3V logic levels. 3.3V CAN transceivers use a 3.3V VCC supply voltage…

  • [FAQ] Can I leave "...." pin floating on my I2C I/O expander or I2C switch? (INT, Reset, Port I/O, ect.)

    For I2C I/O expanders and switches, what happens if I leave a pin floating (such as an interrupt pin, Reset pin, I/O pin, ect.)?
