5 / 6 page 5 www.fairchildsemi.com 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.
