DC Electrical Characteristics
Note 5: An external driver must source at least the specified current to switch from LOW-to-HIGH.
Note 6: An external driver must sink at least the specified current to switch from HIGH-to-LOW.
Note 7: This is the increase in supply current for each input that is at the specified voltage level rather than V
Dynamic Switching Characteristics
Note 8: Characterized in SOIC package. Guaranteed parameter, but not tested.
Note 9: Max number of outputs defined as (n). n
