SN75452B: SN75452BDR extended temperature version

Part Number: SN75452B
Other Parts Discussed in Thread: SN55452B

I am currently using your SN75452BDR in an existing design and now need that unit to operate in an extended temperature environment. I will be redesigning the PCB to accommodate this. I am planning on using the SN55452BFK for this new application.  Other than the temperature they appear to be the same, could you confirm. I found one source that listed the number of bits per element on one at 2 verses 1 on the other,  How does this exactly translate to the component performance?

    Hi Michael,

    Welcome to e2e!

    That's correct, the two devices are functionally the same except for operating temperature and package. Both have two channels and the same logic configurations - where do you see the bits per element discrepancy?

    Thanks,

    Patrick

    Great to know, thanks. I will spec the SN55452B in the new design

    It is listed on the Digikey website under the product attributes for each of the two components. Until I did a more detailed look at the spec sheet, the SN554552 series didn't show up under their parameter search.
