SN75LBC184: Part number designations

Ian Paull

Part Number: SN75LBC184
Other Parts Discussed in Thread: SN65LBC184

What are the meanings of the SN65 and SN75 designations?

Are the parts actually identical?

Thanks.

    Hi Ian,

    Essentially SN65 means industrial temperature range (-40C to 85C) and SN75 means commercial temperature range (0C to 70C) at least on RS-485 / RS-422 devices - I am not sure if there are exceptions in some of our other product groups.

    They are essentially the same device - but we guarantee performance across a larger temperature range and our qualification is done at the higher temperature range for the SN65 variant. But if you were to switch the SN75LBC184 with an SN65LBC184 there really probably won't be too much of a difference in performance - if any really. 

    Please let me know if you  have any other questions!

    Best,

    Parker Dodson
