DC Electrical Characteristics
Note 4: An external driver must source at least the specified current to switch from LOW-to-HIGH.
Note 5: An external driver must sink at least the specified current to switch from HIGH-to-LOW.
Note 6: This is the increase in supply current for each input that is at the specified voltage level rather than VCC or GND.
Dynamic Switching Characteristics (Note 7)
Note 7: Characterized in SSOP package. Guaranteed parameter, but not tested.
Note 8: Max number of outputs defined as (n). n
1 data inputs are driven 0V to 3V. Output under test held LOW.
