Hi Team,
It is mentioned in the datasheet that VCCA must be less than or equal to VCCB (except during power-on transient time), do you have a number for the "power-on transient time"?
In my application, VCCA will always be supplied by 3.3V while VCCB will ramp from 0 to 3.3V at system power-up, also OE is being pulled high to VCCB. We're worried after OE reaches 2.145V (0.65*VCCA) there may be some issue as VCCA will be larger than VCCB during VCCB ramps from 2.145V to 3.3V. So we're thinking if the ramp-up time falls within the "power-on transient time" then that should be OK.
Please let me about know your thoughts.
Thanks!
Roy
