Our customer is considering to use TS3A5223 to switch I2C bus to select one of the two I2C master.
Q1). Can TS3A5223 be used to switch I2C Bus ? I believe there is no problem.
Q2). Since the absolute maximum rating is 4.3V, I believe the device would not get damaged even 3.3V applied to the NC/NO/COM pin when device not powered up. Am I correct ?
One of the I2C master uses separate power suppy (bus pull up voltage) and there is a case where bus pull up is enabled and TS3A5223 is powered down.
Q3). What is the reason that the maximum recommended VNC/VNO/VCOM is limited to "VCC" ?
