Part Number: SN65HVD55
Other Parts Discussed in Thread: THVD1512

Hi team,

My customer wants to find a pin for pin replacement part for ISL83080EIBZ-T.

But seems that all of our transceivers define both pin13 and pin14 as Vcc. But for ISL83080, pin 13 is NC.

The best fit seems to be THVD1552DR, but the datasheet shows that two pins are not internally connected.

So I want to know for SN65HVD55, if the case is different.

Regards,

Xiaoying,

The best replacement for the ISL83080 is the THVD1512.

To answer your question, my assumption is that they are also not connected on the SN65HVD55 and must both be supplied. I will verify this with our design team though.
