A pull-up resistor of <10 k between OE/ ST pin and Vdd is recommended in high noise environment. 4. A capacitor value of 0.1 F between Vdd and GND is recommended. Absolute Maximum Attempted operation outside the absolute maximum ratings of the part may cause permanent damage to the part. Actual perfor- mance of the IC is only guaranteed within the operational specifications, not at absolute maximum ratings. Parameter Min. Max.
