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:
CD4049UBMJ/883
Possible TI replacement parts:
CD4049UB-MIL
CD4049UBF3A
CD4049UBFB (M38510/05553BEA)
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?
Thanks,
Mary Beth
