SN74HC594: Cross

Part Number: SN74HC594
Other Parts Discussed in Thread: SN74LV165A, SN74AHC594, SN74LV594A, , SN74LS165A, SN74HC165, SN74ALS165, CD74HC165

Team, 

Customer has to dual source all their components.

They are asking if we have pin compatible crosses (Q1 or catalog) for: SN74HC594DR and SN74LV165A. 

They are also asking about MAX7317AEE+T, which i don't see a cross for. 

Thank you for your inputs

    Hi Viktorija,

    Are you wanting other options for the same function? Not sure what to cross when you are providing our part numbers.

    For the MAX7317AEE+T, we don't support these types of devices, you may have better luck with the Interface team.

    I know, it's confusing. Yes, we are ultimately second sourcing ourselves. It's the way for customer to protect their design, should there be any supply chain issues. And I would rather have them put down two TI options, and add our comp.. 

    If you have alternatives to the two TI parts, that would offer same/similar performance, in pin compatible form - let me know. 

    Thanks

    TI does not make any SPI I/O expanders.

    To get pin-compatible crosses, you have to look for the name model number in another family.

    For the SN74HC594: SN74AHC594, SN74LV594A.
    For the SN74LV165A: CD74HC165, SN74ALS165, SN74HC165, SN74LS165A.

    I do not know whether the electrical characteristics of those match the actual requirements.

    Hi Viktorija,

    I understand more now. Clemens provided some good alternatives, but he also brings up a good point that these devices don't share identical parameters.

    To narrow down the list, I am suggesting the devices which will be closest parametrically as to reduce any issues caused by different performance.
