Would ti be able to provide a model for SN54AC74 ready for use within LTSpice? If not, can one be created. Thank you.

    Hi Joe, I can submit a request for a TINA-TI or IBIS model, but I will need business case information (# of units/year, company name, # of years).

    TINA-TI is a free simulator from TI that is similar to LTSpice. If you have to use LTSpice, you will need an unencrypted model which may require an NDA. See this post: e2e.ti.com/.../1230055

    In what application are you using the SN74AC74?

    Hello Ryan,

    Number of units per year are around 10K. Company name is Williams International. The SN74AC74 is being used in a vehicle for predominately monitoring fuel.

    Unfortunately the design has been modeled in LTSpice, so to go back and re-do would absorb much time currently not available as the program is close to launching.

    If you could please create for LTSpice, it would be appreciated? Thanks.
