4 / 7 page www.fairchildsemi.com 4 DC Electrical Characteristics (Continued) 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 VCC 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. AC Electrical Characteristics Note 10: All typical values are at VCC 3.3V, TA 25 qC. Capacitance (Note 11) Note 11: Capacitance is measured at frequency f 1 MHz, per MIL-STD-883B, Method 3012.
