† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

This is a stress rating only and functional operation of the device at those or any other conditions above those indicated

in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended

periods may affect device reliability.

Note 1: VDD pin should be filtered with a 0.1 µF capacitor.

2: tSU is time to 100 ppm stable output frequency after VDD is applied and outputs are enabled.

3: See the Output Waveform section and the Test Circuit for more information.

4: Output is enabled if pad is floated or not connected.
