Counter Dividers FAQ

How should the VBB pin be handled if single-ended input is used?

Connect the unused differential input to the VBB pin to serve as a switching reference voltage. Decouple VBB and VCC with a 0.01 µF capacitor and limit current sourcing or sinking to 0.5 mA.

What is the behavior of the Q output when inputs are left open?

The Q output will default LOW when the inputs are open or at VEE. Pins defaulting LOW ensures a defined state during power-up or fault conditions.
