Typical
current is defined as conventional current coming out of (sourced from) the specified device terminal.
data is at T
A
= 25°C. They are for initial design estimations only, and assume optimum manufacturing and application
conditions. Performance may vary for individual units, within the specified maximum and minimum limits.

In these tests, the vector
X
is intended to represent positive and negative
fi
elds sufficient to swing the output driver between fully OFF
and saturated (ON), respectively. It is NOT intended to indicate a range of linear operation.
4
Noise specification includes both digital and analog noise.
