SN65C1168E: Difference between SN75C1168NS and SN65C1168ENSR

Part Number: SN65C1168E

Hi, 

Since the SN75C1168NS is EOL, we are investigating the recommended replacement SN65C1168ENSR.

Could you tell me the difference between SN75C1168NS and SN65C1168ENSR?

Thanks,

Conor

    "E" means better ESD protection.

    "R" means that the chips are packaged not in a tube but on a reel.

    Hi Conor,

    There are a few differences.

    1. The temperature range on the SN65C1168ENSR is larger than the SN75C1168NS - the prefix SN65 typically denotes a temperature range of  -40C to 85C while SN75 denotes a temperature range of 0C to 70C. This is not a problem from a use case point of view when switching from a SN75 to a SN65 as the temperature range increases so any SN65 device will be able to handle the temperature range of an application that was previously using an SN75.

    The other two are as Clemens mentioned:

    2. "E" denotes enhanced ESD protection - this will just add additional protection from a system level if you replaced the SN75C1168NS with the SN65C1168ENSR - so its a beneficial change and wouldn't negatively impact use case. The SN75C1168NS has no listed ESD protection and the SN65C1168ENSR has the following ESD specs:

    3. The "R" at the end of the SN65C1168ENSR just denotes that the NS package of the SN65C1168E will come in a reel instead of a tube when ordered. 

    Please let me know if you have any other questions!

    Best,
