Please help me to understand the differences between the following parts. I'm trying to pick the one closest to the obsolete P/N. They all seem to be 16 pin CERDIP packages in the mil temp range :
Obsolete part National’s:
Possible TI replacement parts:
Also, I understand what MIL-STD-883 is but what did National mean by the suffix /883? Has it actually had the testing or was it made on the same manufacturing line with the same processes as those that get the /883 testing?
Hi Mary Beth,
The CD4049UBMJ/883 would be a device processed according to MIL-STD-883 Level B. That has been superseded by MIL-PRF-38535 QML Class Q. The orderable part number from TI is CD4049UBF3A. An explanation of the part nomenclature can be found at http://www.ti.com/pdfs/hirel/hirel_product_nomenclature.pdf on page 6.
Let me know if you have any other questions.
