Provide case details or comments: I wish to replace the obsolete CM1233-08DE from ON Semiconductor, datasheet attached, with the TPD8S009DSMR, if you can confirm it is functionally equivalent. I need help with the pin mapping in my schematic. I must have these questions answered in order to use the TPD8S009 in our Abbott Labs production. I've attached the datasheets and a which shows the Cadence blocks I have and how I'm using the CM1233-08E in my schematic. If anyone can help me with this, my email is David.Tipotsch@abbott.com. I can send you the datasheet for the CM1233-08DE and my Cadence blocks and how I'm using the CM1233-08DE in my schematic presently as well as the TPD8S009DSMR datasheet if you need it to answer my question. Alternatively, if someone could just clarify for me what the differential line inputs and outputs are for the TPD8S009DSMR, that would be helpful.
Here are my specific questions:
1) Does it take two TPD8S009DSMR to replace one CM1233-08DE (which handles 8 differential pairs)?
2) What is the mapping of the CM1233-08DE pins OUT_1+, OUT_1-, IN_1+, IN_1-, OUT_2+, OUT_2-, IN_2+, IN_2-, OUT_3+, OUT_3-, IN_3+, IN_3-, OUT_4+, OUT_4-, IN_4+ and IN_4- to TPD8S009DSMR pins? What are the corresponding TPD8S009DSMR pins?
