FAQ: Logic and Voltage Translation > Ground-Level Translators >> Current FAQ
Ground shifting requires the voltage supplies to be separated and to remain within the recommended operating conditions.
In the image below, GNDB shifts by -5V due to parasitic effects while A-Side remains within the device limits. However, B-side exceeds its supply-to-ground absolute maximum rating. To avoid this condition, it is recommended that both supplies and their respective grounds remain isolated from each other.
