SN74HCS32-Q1: Request to Functional safety FIT value(SN29500-2)

Part Number: SN74HCS32-Q1
Other Parts Discussed in Thread: INA148-Q1, TCAN1042-Q1

I inquire about the functional safety FIT(Application FIT Rate) value for the device below.


Standard is SIEMENSE SN29500-2.

(it is not a request for a JEDEC-based technical fit value.)

* PART NO

1. SN74HCS32QDRQ1

2. TLV7031QDBVRQ1

3. TPS3823-50QDBVRQ1

4. AMC1311BQDWVRQ1

5. TCAN1042GDRQ1

6. INA148-Q1

7. INA199B2QDCKRQ1

Please inquire about the detailed calculation formula for the FIT value.

Please let me know if there is any additional information you need.

  • Hi,

    The picture below is for SN74HCS32QDRQ1. You can find this in the "Quality, Reliability, Packaging" section in our ti.com product page:

    You can refer to this: https://www.ti.com/lit/sloa294 for how TI gets these results. 

  • Thank you for your reply.
    However, it is not the answer I want.
    The values shown are technical FIT values based on JEDEC.

    I want functional safety FIT value based on SN29500.

    Taking the TCAN1042-Q1 as an example, the following documents are required.
    www.ti.com/.../slla502
    What we can see from that document is that the Reference FIT value (SN29500) = 20FIT.

    What I want is the Application FIT value.

    And I need FIT values for all part no. below.
    Please check again.
