TXB0108: Sneak current to VccA from the A port -side circuit.

Takahiro Saito

Part Number: TXB0108

Hello team,

Is there no sneak current to the VccA from the A port -side circuit on the condition that the port A side circuit is ON and the VccA is OFF?

Hi Saito-san,

Taka Saito san ,

As long as the Vcca(or Vccb) is held at 0V and not left floating, there is no concern with the current leakage into the Vcca from the Aside I/O port as the TXB0108 is rated for Ioff partial power down protection circuitry .
