SN54S139: MIL-STD-883

Part Number: SN54S139

Since M38510/07702BEA is not supported - can the SN54S139J ceramic DIP chip be screened to 883 to be equivalent ?

What is the 7700401EA version  ?

    Hi Steve,

    I feel like i came in on the end of a conversation here.

    To be clear, I think you're looking for a replacement for M38510/07702BEA because you need that device and we no longer produce it. You need the replacement to meet MIL-STD-883.

    Is this correct?

    Do you have any additional details regarding the application?  Is this a direct replacement (pin to pin only), or a functional replacement (different package/logic family is ok)?  Any extra info is helpful for trying to find a replacement.

    Hi Emrys,

    Yes - I need to replace M38510/07702BEA - it goes on a logic board with a whole bunch of "S" logic family chips so I do not want to mix in the newer "LS" M38510 part.

    I have now found that 7700401EA is a DLA specification that essentially reactivates M38510/07702BEA - and at least at one time you would produce to that.

    Do you still see 7700401EA as an orderable part or is it EOL ?

    Hey Steve,

    Yes, the 7700401EA orderable part number is still listed as active and available to order in our system.

    I would recommend reaching out to your company's TI sales rep for a quote on the device.
