I am using "54VCXH163245" bidirectional level shifter in one of my ongoing projects. I am using VCCA as 3.3V and VCCB as 1.8V. My queries are: 1. Is there any power-on sequencing requirement for 1.8V and 3.3V for this device.?

However, For similar level translator device like "54AC164245", there is an explicit requirement of sequencing of 3.3V and 5.0V . Please confirm and clarify.Then datasheet of device "54VCXH163245" says VCCA must be higher or equal to VCCB, but for "...
