Part Number: LM139AQML-SP

Hi Kirby and team,

What are the differences between the "LM139AW-SMD" and the 5962 version? Does the -SMD version refer to the commercial or MIL version of the device?

Thanks,

AH

  • Hello Alpha,

    I assume the "5962" SMD# you are referring to is 5962-8773901DA.

    I quoteth from Kirby:

    "Before the acquisition, TI and National offered some products that used the same SMD number.

    After the acquisition, it was decided that if a customer ordered the 5962 number, they would get the TI version.  To get the National version, the customer had to order by the NSID (full National part number)."

    The 5962-8773901DA is a LM139AWB, which is a native Texas Instruments device, which is on the LM139A-MIL datasheet.

    The LM139AW-SMD is the original National Semiconductor device, which is on the LM139AQML datasheet.

    So, if you order the "5962-8773901DA", you get the TI version. If you order "LM139AW-SMD", you get the National version.
