Part Number: TUSB4020BI

Hi Team,

According to datasheet, pull-down resistor of TEST pin is 1kohm.

However, a recommended pulled down resistor is 4.7khom in the TUSB4020BI Schematic Checklist.

I understand that both(1kohom and 4.7kohm) can be used.

Is my understanding correct?

If no. could you please let us know a correct value?

Both 1k and 4.7k ohm pulldown resistor can be work. Once TEST pin is pulldown, it's not in test mode.
