*Typical data are for initial design estimations only, and assume optimum manufacturing and application conditions. Performance may vary for
individual units, within the specified maximum and minimum limits.
For input and output current specifications, negative current is defined as coming out of (sourcing) the specified device pin.
Specifications throughout the allowed operating temperature range are guaranteed by design and characterization.
