In OE or ST mode, a pull-up resistor of 10 k or less is recommended if pin 3 is not externally driven. If pin 3 needs to be left floating, use the NC option. 2. A capacitor of value 0.1 F or higher between Vdd and GND is required. Table 3. Absolute Maximum Limits Attempted operation outside the absolute maximum ratings may cause permanent damage to the part.
