FAQ: Logic and Voltage Translation > Ground-Level Translators >> Current FAQ
The TXG product family can be used as a regular level translator (VCCA > VCCB or VCCA < VCCB) or in a buffer configuration (VCCA = VCCB).
If a user doesn’t need ground shifting but requires a level translator with exceptional output skew and data rate parameters, they can simply tie GNDA and GNDB together.
If ground shifting is needed, we require VCCA/GNDA and VCCB/GNDB to be separated, similar to the image below.
