  • RE: SN74LV125A: we use buffer in STO circuit and this buffer cannot be recognized as a fail-safe part.

    Resolved
    Hi Clemens, thank you for your reply, we are now kind of changing our circuit, instead of buffer, we use digital isolator, which is listed in TI safety products. For buffer, if the damage effects not clarified by TI, we have to assume the worst effect…

  • SN74LV125A: Buffer distributing clock frequency from oscillator to 4 MCUs

    TI Thinks Resolved
    Part Number: SN74LV125A Other Parts Discussed in Thread: SN74LVC125A , SN74AUC125 We are using the buffer SN74LV125ADGV. The input , given to the buffer, is a 48MHz oscillator frequency and the output is connected to 4 MCUs, as external clock input, through…

  • SN74LV125A-Q1: Thermal pad connection to GND or N/C?

    Resolved
    Part Number: SN74LV125A-Q1 Hi, I am using SN74LV125A-Q1 buffer in my design. The datasheet doesn't provide any information about the connection of the thermal pad. Can it be connected to GND or does it need to remain N/C?

  • RE: SN3257-Q1: SPI/I2C/Control pins isolation from the uC

    Resolved
    An isolator like the ISO7041-Q1 makes sense only for galvanic isolation. The SN3257-Q1 would be able to disconnect the signals. Alternatively, use any buffer with Ioff protection, e.g., SN74LV125A-Q1 or SN54LVTH244A-SP.

  • SN74LV125A: what is the test condition for Volp and Vohv

    Resolved
    Part Number: SN74LV125A Hi In the datasheet the value of typical Vol(output ground bounce) and Vohv (output voh undershoot) is seems a key future for SN74LV125A, (compare to some SN74xxx logic device) But I can't not find its test condition. or detail…
