Translators, Level Shifters FAQ

What is the relationship between VCC(A) and VCC(B) during operation?

VCC(A) must be less than or equal to VCC(B) during normal operation.

How does the device handle power-down conditions?

If either VCC(A) or VCC(B) is at GND level, the device enters power-down mode, and IOFF circuitry disables outputs to prevent backflow current.
