Part Number: SN74AVCH2T45
We intend to use SN74AVCH2T45 to translate the signal of SFP+ module(such as RX RATE , TX DISABLE) from 1.8V to 3.3V , and the 3.3V side will be connected to the SFP+ .
So , does the hot-plug of SFP+ module can cause damage to SN74AVCH2T45 ? P.S. VCC of SN74AVCH2T45 will not power down in the whole process.
Hope for your reply

In reply to Emrys Maier:
I drew a diagram to indicate the relevant system . And the signals need to be translate are showed in the table from SFF-8431
For your questions ,
will people be touching the connector? --------- In the upper diagram , people will not touch the connector , but they will touch the module . But , the antistatic gloves are required
Is your system designed to connect ground FIRST, the VCC, and _finally_ digital I/O lines? --------- Yes
What will the voltage be on any one I/O line when the connection is made? -------- I did not get the point . Can the diagram above explain the problem?
we would need to know the load capacitance -------- Sorry , I really don't know
If your need more other info , please let me know
