DC Electrical Characteristics
Note 4: All typical values are at V
Note 5: Applies to bushold versions only (74LVTH2244).
Note 6: An external driver must source at least the specified current to switch from LOW-to-HIGH.
Note 7: An external driver must sink at least the specified current to switch from HIGH-to-LOW.
Note 8: This is the increase in supply current for each, input that is at the specified voltage level rather than V
Dynamic Switching Characteristics
Note 9: Characterized in SOIC package. Guaranteed parameter, but not tested.
Note 10: Max number of outputs defined as (n). n
AC Electrical Characteristics
Note 11: All typical values are at V
Note 12: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (t
