LSF0102: Question about a customer specific circuits

Part Number: LSF0102
Other Parts Discussed in Thread: PCA9306,

Tool/software:

Hello,

Q1:
At the following circuits, when Vref(A) = 3.3V enable signal = 0V and Vpu = 3.3V, B1 and B2 are hi-impedance and device2 and device3 can do I2C communication?

Q2:
How about PCA9306 instead of LSF0102? The answer is the same as Q1?

Best regards,

1. The I/O pins are in the high impedance state only when EN is low.

2. The LSF0102 and PCA9306 are identical.

Clemens,

Thank you for your response.
Let me confirm about Q1 more.
So, do you mean device2 and device3 can do I2C communication under the conditions?

Best regards,
