Note 10: 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 11: 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 12: 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 13: The 3-STATE delay times are dominated by the RC network (500Ω, 250 pF) on the output and has been excluded from the datasheet.
