4. In OE or

mode, a pull-up resistor of 10 kΩ or less is recommended if pin 1 is not externally driven. If pin 1 needs to be left floating, use the NC option.

5. A capacitor of value 0.1 µF or higher between Vdd and GND is required.

Table 5. Absolute Maximum Limits

Attempted operation outside the absolute maximum ratings may cause permanent damage to the part. Actual performance of

the IC is only guaranteed within the operational specifications, not at absolute maximum ratings.
