Hi,

Do you have a data which express the typical value, distribution and/or statistical data of Tpd?


Thank you for your support in advance.

Ken

    Hi Kenichiro,

    What voltage are you planning to operate at?

    For now I can refer you to the Typical Charactersitics section on page 7 of the SN74LVC1G126 datasheet. There you will find two plots that show tpd for various load capacitance. This is the non-Q1 version but the parts are essentially the same.

    Hope this helps.

    Regards,

    Joe

    Hi Joe,

    It's good information! Thank you.
    I have shared the information from non-Q1 with my customer.

    He would use SNLVC1G126-Q1 with 3.3V power supply.
    It's great if you have specific data for this condition.

    Thanks,
    Ken

    Hi Joe,

    Do you have any further information on this??

    Hi Ken,

    The Q1 version is essentially the same part as the non-Q1, so the figures on page 7 of the the SN74LVC1G126 datasheet are accurate and can be used. This data was tested for 3V +/- 0.3V.

    How is the part going to be operated? You mentioned 3.3V power supply, but are there other operating conditions that need to be concidered, such as temperature? Is there a maximum propagation delay for the system that the customer is worried about?

    Depending on the load capacitance the part sees, the typical propagation delay can range from ~2.5 ns to ~7.5 ns (low to high transition) and ~2ns to ~5ns ( high to low transition).

    Please provide more detail.

    Thank you,

    Joe

    Thanks, Joe,

    I just wanted to know whether you have anything specific information for SN74LVC1G126-Q1. It's okay, I have asked customer to check the information on the datasheet of SN74LVC1G126 (non-automotive) as reference.

    Thank you for your support!
