PCA9306: start up time after device is enabled

Part Number: PCA9306

Hi Team,

I have a question about start-up time after device is enabled.

How long do we take start-up time to operate normal operation with below condition?

VREF1=1.8V

VREF2=3.3V

EN= 0 to 3.3V

the same circuit with datasheet figure 8.

Thanks,

Kai

    Hello Kai,

    The part can start translating as soon as the voltage is at the desired voltage level.  There is little to no delay.  The limiting factor is going to be the start up time or your power supply or the RC time constant of attached to Vref2 and En pins  using the 200k Ohm resistor and what ever decoupling capacitor you have on the design, this assumes you are powering the translator from a GPIO or something similar.
