Note 1: These parameters are not production tested but are guaranteed by design, characterization, and
correlation with statistical process control.
Note 2: Current sourced by a pin is reported with a negative sign.
Note 3: Refer to the VC Bias section in the Application Information for details on the VC requirement to meet the
MOSFET V_GS requirement.
