description/ordering information (continued)

Information at the data (D) inputs meeting the setup time requirements is transferred to the outputs on the

positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a particular voltage level and is not

related directly to the transition time of the positive-going edge of CLK. When CLK is at either the high or low

level, the D input has no effect at the output.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.

2. The package thermal impedance is calculated in accordance with JESD 51-7.
