Hello,
I haven't seen anything about the effects of transient loss of a VCCA or VCCB power supply in the datasheet.
In our design, there may possibly be the loss of one of these voltages (3.3V and 1.8V) for a maximum time of 65ms.
Can you confirm that there will be no other effect than the possibility of having the outputs in an erroneous state and this regardless of:
- the power supply configuration: - VCCA = 3V3 and VCCB = 1V8 or VCCA = 1V8 and VCCB = 3V3,
- or the direction, from B to A or from A to B.
Thank you in advance,
Best regards
Pierre
