ISO6731: ISO6731FDWR related issues

Part Number: ISO6731

Hi，

The power supply voltage range in the ISO6731FDWR manual is 1.71V to 1.89V and 2.25V to 5.5V, as shown in the following figure. May I ask if the voltage devices in the range of 1.89 to 2.25 cannot work? Why?

Thanks！

    Hello,

    Thank you for your question.

    The supply voltages that are listed in the datasheet are 1.71V-1.89V and 2.25V-5.5V, as you have already seen.

    Applying a voltage for VCC that is not within the ranges violates the recommended operating conditions. We cannot guarantee the normal operation of this device when the VCC is between 1.89V to 2.25V.
