Note 8: All outputs loaded; thresholds on input associated with output under test.
Note 9: Maximum test duration 2.0 ms, one output loaded at a time.
Note 10: Plastic DIP package.
Note 11: Max number of outputs defined as (n). Data Inputs are driven 0V to 3V. One output @ GND.
Note 12: Max number of data inputs (n) switching. (n 1) inputs switching 0V to 3V (ACTQ). Input-under-test switching: 3V to threshold (VILD), 0V to threshold
(VIHD), f =1 MHz.

Note 14: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The speci-
fication applies to any outputs switching in the same direction, either HIGH to LOW (tOSHL or LOW to HIGH (tOSLH). Parameter guaranteed by design.
