Extended AC Electrical Characteristics
(SOIC Package)
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 delay with 250pF 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 11: 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 12: The 3-STATE delay times are dominated by the RC network (500 , 250 pF) on the output and has been excluded from the datasheet
Skew
(SOIC Package)
Note 13: 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 14: 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.
Note 15: 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
to-LOW (t
Note 16: This describes the difference between the delay of the LOW-to-HIGH and the HIGH-to-LOW transition on the same pin. It is measured across all
the outputs (drivers) on the same chip, the worst (largest delta) number is the guaranteed specification. This specification is guaranteed but not tested.
Note 17: Propagation delay variation for a given set of conditions (i.e., temperature and V
