Translators, Level Shifters FAQ

What happens to the Q output under open input conditions?

Under open input conditions, the /D input is biased at a VCC/2 voltage level while the D input is pulled to ground, forcing the Q output LOW to provide added stability.

How should the VBB output be handled if used?

If the VBB output is utilized, it should be bypassed to VCC with a 0.01 µF capacitor.
