AC Electrical Characteristics
Note 10:
Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (t
OSHL
) or LOW-to-HIGH (t
OSLH
).
Capacitance
(Note 11)
Note 11:
Capacitance is measured at frequency f
1 MHz, per MIL-STD-883, Method 3012.
