CD4068B: CD4068BF vs. CD4068BF3A

Juan Aparicio Jimenez

Part Number: CD4068B

Hello team,

Could you list us all differences between following PNs:

CD4068BF

CD4068BF3A

What is the meaning of the “3A” suffix?

Thanks in advance,

Juan.

These OPNs are not for the CD4068B but for the CD4068B-MIL.

"3A" indicates MIL-PRF-38535 qualification; see High Reliability Part Numbering System.

Hello Clemens,

Both PNs, CD4068BF and CD4068BF3A, are from your CD4068B-MIL series.

If only CD4068BF3A is MIL-PRF-38535 qualified, why would CD4068BF belong to CD4068B-MIL and not CD4068B?

Thanks,

Juan.

(I am not, and have never been, a TI or Harris employee.)

CD4068BF and CD4068BF3A are the same chip itself (in a ceramic DIP package). MIL-PRF-38535 is testing and paperwork.
