Part Number: SN54F521

Hi,

We would like to use comparator part # SN54F521J in one of our new design. But online stock for this part found to be very less. Is this part a recommended one for new designs?

Can we expect a Lifecycle of more than 10 years? Please confirm.

    Athun,

    This device is an Active product.   We do not have plans to discontinue this device.

    Here is a quote from a document located at www.ti.com/quality It is in the General Quality Guidelines document.

    TI’s Product withdrawal/discontinuance process complies with J-STD-048, latest issue. TI makes an effort to not obsolete products out of convenience. Convenience means: low running device, poor yields, limited customer adoption or similar items. TI’s obsolescence withdrawal schedule provides a longer lead time than the industry standard. TI allows 12 months for the last order and an additional 6 months to take final delivery of obsolete items. In rare circumstances, an accelerated withdrawal schedule may be necessary. In such cases, TI will communicate the last buy and final delivery dates in the EOL notice, along with an explanation of the circumstances necessitating the early withdrawal.


    With respect to product availability.  It would be advised to book the order with a TI authorized distributor.  They can procure the inventory and advise on lead times if product is not in stock.
