Dear Members
I is requesting the FIT value for TLC1543IDB and PCM1754DBQR.
I checked this on "MTBF / FIT estimator" and "Quality, reliability & packaging data download" but there was no result.
Could anyone let me know the FIT value for TLC1543IDB and PCM1754DBQR?
Regards,
Hi Murakami-san,
We are looking into this for you. It may take another day or two to find out why the on-line MTBF tool does not have any detail for these devices.
Dear Tom
I'm waiting for your answer.
Please let me know the status of my request.
Regards,
Hiroyuki Murakami
Hi Murakami-san,
My apologies for the delay here. I went through our quality control engineers and have found no FIT data for these two devices. They are old products and have not seen any customer returns in over five years.
Dear TOM
Please calculate the fit value from the failure rate data in the market.
Or please estimete Fit value from device processes.
I request one of the following Fit values:
1) Fit value based on market failure rate
2) Estimated Fit value from device process
3) Fit value from market failure rate and estimated Fit value from device process.
Please document the Fit values estimated using these methods and send them to me.
Regards,
Hiroyuki Murakami
I see that the TLC1543 has recently gone to 'Last Time Buy' status. As it nears EOL, are you working on a new project? If so, you should consider an alternative device. The ADS7956 might be a suitable alternative for you.
Dear Tom
Thank you for giving me the EOL information.
I do not request FIT values for TLC1543IDB.
But I only request the Fit value of PCM1754DBQR.

Hello Hiroyuki,
PCM1754 was released 2 decades ago, upon a technology that is even older than that and unfortunately we can not provide FIT value for this device.
We apologize for the inconvenience that it might create.

Dear Arash Loloee
I understand that you cannot send me that document.
Thank you very much.
I'm canceling this request.
