Notes:
5.
Typical values are at V
=5.0V, T
=+25C ambient.
6.
This parameter is specified but not tested.
7.
Pins with bus hold are described in Pin Description.
8.
Not more than one output should be shorted at a time. Duration of short should not exceed one second. The use of high-speed test apparatus and/or sample
and hold techniques are preferable in order to minimize internal chip heating and more accurately reflect operational values. Otherwise prolonged shorting of
a high output may raise the chip temperature well above normal and thereby cause invalid readings in other parametric tests. In any sequence of parameter
tests, I
tests should be performed last.
9.
Tested at +25C.
