The pull-up resistor will range from 13.2K to 100K Ohms. The strength of the pull-up will decrease as VCCO decreases (resistor value increases). The strength of the pull-down will have the opposite affect when VCCO decreases. As VCCO decreases, the strength of the pull-down increases (resistor value decreases). In either case, the pull-up or pull-down resistor range is sufficient to either hold a logic level High or logic level Low.
