Note 7:
Not more than one output should be shorted at a time, and the duration should not exceed one second. For devices, with feedback from the outputs,
where shorting the outputs to ground may cause the outputs to change logic state an equivalent test may be performed where V
O
=
2.125V with the minimum
and maximum limits reduced by one half from their stated values. This is very useful when using automatic test equipment.
Note 8:
With all outputs OPEN, I
CC
is measured with the Q and Q outputs HIGH in turn. At the time of measurement the clock is grounded.
