AC Electrical Characteristics
AC Operating Requirements
Extended AC Electrical Characteristics
Note 3:
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, 3-STATE-to-HIGH, etc.
Note 4:
These specifications guaranteed but not tested. The limits represent propagation delays with 250 pF load capacitors in place of the 50 pF load
capacitors in the standard AC load. This specification pertains to single output switching only.
Note 5:
Skew is defined as the absolute value of the difference between the actual propagation delays for any two outputs of the same device. The specifi-
cation applies to any outputs switching HIGH-to-LOW, (t
OSHL
), LOW-to-HIGH, (t
OSLH
), or HIGH-to-LOW and/or LOW-to-HIGH, (t
OST
). Specifications guaran-
teed with all outputs switching in phase.
