Note 2. .For conditions shown as MIN or MAX, use the appropriate value specified under “Recommended
Operation Conditions”.
Note 3. All typical values are at V
CC
= 5V, T
A
= +25C.
Note 4. Not more than one output should be shorted at a time, and duration of the short−circuit
should not exceed one second.
Note 5. For certain devices where state commutation can be caused by shorting an output to ground,
an equivalent test may be performed with V
O
= 2.125Vand the minimum an maximum limits
reduced to one half of their stated values.
Note 6. With all outputs open, I
CC
is measured with the Q and Q outputs high in turn. At the time of
measurement, the clock input is grounded.
