Notes:
7. 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.).
8. This specification is guaranteed but not tested. The limits represent propagation delay with 250pF load capacitors
in place of the 50pF load capacitors in the standard AC load. This specification pertains to single output switching
only.
9. 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 250pF load capacitors in place of the 50pF load
capacitors in the standard AC load.
10. The 3-STATE delays are dominated by the RC network (500Ω, 250pF) on the output and have been excluded from
the datasheet.
