Current into a device pin is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to Ground

unless otherwise specified.

(3)

Specification is ensured by characterization and is not tested in production.

(4)

Specification is ensured by design and is not tested in production.

(5)

When clock input is in overdrive ( Vin = 3.3 V ) and then stop clock is applied, it is recommended to set input clock to a low state.
