Hello Sopatopa,
The minimum time is ~100us. So having less than 1ms should be fine.

Hello sopatopa,

The voltage operation range of this device goes from 3V to 3.6V. Therefore, 1V is enough.

Hello,Joel

Thanks for your reply.
I will explain this information to customers.

However, I received the following reply on other products.

> SN65LVDT100: Restart time (Power OFF -> Power ON) and Power restart Voltage (required falling voltage)

there is not a specific requirement of how low the voltage needs to be.
However, please notice that the device output will be undetermined during that period.
