DC Electrical Characteristics
Note 4:
Applies to Bushold versions only (74LVTH2245).
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
CC
or GND.
Dynamic Switching Characteristics
(Note 8)
Note 8:
Characterized in SOIC package. Guaranteed parameter, but not tested.
Note 9:
Max number of outputs defined as (n). n 1 data inputs are driven 0V to 3V. Output under test held LOW.
