Input Capacitance
Output Capacitance
Typical values are at V
=5.0V, T
=+25°C ambient.
This parameter is guaranteed but not tested.
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
OS
tests should be performed last.
