Hello experts

Is it correct to understand that 1-10, 2-9, 4-7, and 5-6 pins are connected?

I don't understand the text here, and I am confused.

It says:

Not connected; used for optional straight-through routing. Can be left floating or Grounded

I think 6-10 can be either floating or GND, but if that is the case, the signal does not penetrate

Zhou

These pins are not connected at all. You can solder them to the IO1/2/3/4 traces, which makes routing easier.

3 and 8 are connected. The others are not.

Hi J-ZHOU,

As Clemens mentioned the NC pins are not connected internally, this is why they are labeled as NC and can be left floating or grounded.

Most people will route their signals through each input and NC as shown in the datasheet:

Thank you Sebastian

Currently, customer is thinking to use like this:

For ESD protection, they want to input 4 channel signals to 1,2,4,5pin, and get output from pin　9,8,7,6

how should they connect please?

Zhou
