Hi team,

I got question from customer.

When PDB is driven to Low, are SCL and SDA port of DS90UB913A in Hi-Z status?

Hello-

Yes, when PDB is driven low, the I2C pins are high impedance.

Hello,

Thanks for your prompt support.

When VDDIO, VDD_n are not supplied condition, are the I2C pins high impedance?
