(1)

The Electrical Characteristics tables list ensured specifications under the listed Recommended Operating Conditions except as

otherwise modified or specified by the Electrical Characteristics Conditions and/or Notes. Typical specifications are estimations only and

are not ensured.

(2)

Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are referenced to ground

except VOD and ΔVOD.

(3)

Typical values represent most likely parametric norms for VDD = +3.3V and TA = +25°C, and at the Recommended Operation Conditions

at the time of product characterization and are not ensured.

(4)

CL includes fixture capacitance and CD includes probe capacitance.

(5)

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

(6)

Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only.
