3 Summary

Hang time occurs due to the usage of the passFET which is present in any application that uses passive CMOS level translation. I2C level translators such as TCA39306, PCA9306, or I2C CMOS switches such as the TCA9548A all exhibit the behavior. Both types of devices can have this effect on the I2C bus but can most likely not cause data glitches due to the short timing interval.
