Other Parts Discussed in Thread: TS3V713EL

Hi,

I have one question about TS3V713EL. In datasheet, TS3V713EL pin 8 is NC.

1. Should pin 8 be left floating?

2. What is the internal circuit design for pin 8?

3. How about to connect pin 8 to 3.3V?

Thanks.

Johnny,

I apologize this information is not clearly found in this datasheet. I have made a note in our datasheet change backlog to add information on how to terminate the N.C pin 8 of the TS3V713EL IC.

You may leave the pin floating because N.C. pin 8 does not have a bond wire connecting the pin to the internal silicon.

Why would you like to connect pin 8 to 3.3V?

Thank you,

Adam

Adam,

Competitor's device is pin2pin with TS3V713EL, and the pin8 is required pulled up to 3.3V. Customer would like to use the same BOM and connection.

Since pin 8 does not have a bond wire connecting the pin to the internal silicon, is there any risk and other consideration to connect pin8 to 3.3V?

Thanks.

Johnny,

I pulled the PI3V713-A datasheet from pericom's website and see that for the PI3V713-A device you are correct you need to pull up pin 8 Reserved pin "high".

Since the TS3V713EL does not have a bond wire connecting pin 8 to the silicon there you may apply 3.3V to pin 8 without issue.

Thank you,

Adam
