DC Electrical Characteristics (Continued)
Note 5: Applies to bushold versions only (74LVTH322245).
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 VCC or GND.
Dynamic Switching Characteristics (Note 9)
Note 9: Characterized in SSOP package. Guaranteed parameter, but not tested.
Note 10: Max number of outputs defined as (n). n
−1 data inputs are driven 0V to 3V. Output under test held LOW.
AC Electrical Characteristics
Capacitance (Note 11)
Note 11: Capacitance is measured at frequency f
= 1 MHz, per MIL-STD-883, Method 3012.
