Part Number: TCA9802
Hi team,
My customer has questions about level-translating.
According to their design requirements, sometimes VCCA or VCCB will be poweroff while the circuit is working,
Is the device operational with VCCA or VCCB supplies is zero?
Since it says that "The SCLA and SDAA pins enters a high impedance state when either VCCA or VCCB fall below their UVLO voltages. These pins are safe to continue having I2C communication on, even when the device is disabled or has no power."in the datasheet.
Thank you in advance.
