Sample tested during initial release to ensure compliance. All input signals are specified with t
The time required for the output to cross is 0.4 V or 2.4 V.
All timing specifications given are with a 25 pF load capacitance. With a load capacitance greater than this value, a digital buffer or latch must be used. See the
Terminology section and Figure 25.
