Note 5: Max number of outputs defined as (n). n 1 data inputs are driven 0V to 3V. One output at LOW. Guaranteed, but not tested.
Note 6: Max number of outputs defined as (n). n 1 data inputs are driven 0V to 3V. One output HIGH. Guaranteed, but not tested.
Note 7: Max number of data inputs (n) switching. n 1 inputs switching 0V to 3V. Input-under-test switching: 3V to threshold (VILD), 0V to threshold (VIHD).
Guaranteed, but not tested.

Note 8: This specification is guaranteed but not tested. The limits apply to propagation delays for all paths described switching in phase
(i.e., all LOW-to-HIGH, HIGH-to-LOW, etc.).

Note 9: This specification is guaranteed but not tested. The limits represent propagation delay with 250 pF load capacitors in place of the 50 pF load capac-
itors in the standard AC load. This specification pertains to single output switching only.
Note 10: This specification is guaranteed but not tested. The limits represent propagation delays for all paths described switching in phase
(i.e., all LOW-to-HIGH, HIGH-to-LOW, etc.) with 250 pF load capacitors in place of the 50 pF load capacitors in the standard AC load.
Note 11: The 3-STATE delays are dominated by the RC network (500:, 250 pF) on the output and have been excluded from the datasheet.
