Other Parts Discussed in Thread: TXS0102
Hello E2E,
What is the output state or impedance at A side when VCCB and OE is floating but VCCA has bias voltage?
Sincerely,
Jason

The datasheet says:
The TXB0102 device has circuitry that disables all output ports when either VCC is switched off (VCCA/B = 0 V).
But when VCCB is floating, then C4296 might have enough remaining charge so that there is a voltage high enough to power the device.
Please note that the TXB I/Os do not work with pull-up resistors and cannot be used for I²C/SMBUS. The TXS0102 would work in this situation.
Hello Ladisch,
Thanks for your reply.
Assume we change to TXS0102 at the same configuration, what if Vccb is floating and fully discharge, what is the A side pins impedance while VCCA is still biasing?
Sincerely,
Jason
