TXS0108E-Q1: for SPI

David Park

Part Number: TXS0108E-Q1
Other Parts Discussed in Thread: TXB0106-Q1, , TXB0104-Q1, TXB0106, LSF0108

Hi,

Customer would like to using level translation for SPI 1.8V to 3.3V in automotive.

TXB0106-Q1 is considered but 125C operating condition is needed.

So TXS0108E-Q1 is considered.

In the datasheet, TXS0108E-Q1 can be used for push-pull IO.

Is it ok to use TXS0108E-Q1 for SPI communication?

Thanks.

    Hi David,

    I know that SPI is a 4 wire interface, SCLK, SS, MISO & MOSI.

    I would encourage you to consider using the TXB0104-Q1 which is 125C qualified and ideal for push-pull interface.

    Hi Rao,
    Customer needs 6ch translator.
    So TXB0106 and TXS0108 are considered.
    Can't TXS0108 be used for SPI?

    Thanks.

    TXS could be used for push pull interface too.
    with the internal RC time constant to overcome, the data rate can be a challenge. There is LSF0108 which supports 125C but needs external resistors which can be configured to work with the desired data rates as needed.
