DC Electrical Characteristics
Note 2: All outputs loaded; thresholds on input associated with output under test.
Note 3: Maximum test duration 2.0 ms, one output loaded at a time.
Note 4: DIP package.
Note 5: Max number of outputs defined as (n). Data inputs are driven 0V to 3V. One output @ GND.
Note 6: Max number of data inputs (n) switching. (n

AC Electrical Characteristics
Note 7: Voltage Range 5.0 is 5.0V 0.5V.
Note 8: Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs within the same packaged device.
The specification applies to any outputs switching in the same direction, either HIGH to LOW (t
design. Not tested.
