AC Electrical Characteristics
Note 8:
Voltage Range 5.0 is 5.0V
±
0.5V.
Extended AC Electrical Characteristics
Note 9:
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 10:
This specification is 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 11:
3-STATE delays are load dominated and have been excluded from the datasheet.
Note 12:
The Output Disable Time is dominated by the RC network (500
, 250 pF) on the output and has been excluded from the datasheet.
Note 13:
Skew is defined as the absolute value of the difference between the actual propagation delays for any two separate outputs of the same device.
The specification applies to any outputs switching HIGH-to-LOW (t
OSHL
), LOW-to-HIGH (t
OSLH
), or any combination switching LOW-to-HIGH and/or HIGH-
to-LOW (t
OST
).
