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

qC.
Capacitance (Note 11)
Note 11: Capacitance is measured at frequency f
1 MHz, per MIL-STD-883B, Method 3012.
