1 Negative current is de fi ned as conventional current coming out of (sourced from) the speci fi ed device terminal.
2 Typical 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 speci fi ed maximum and minimum limits.
3 In these tests, the vector
X
is intended to represent positive and negative fi elds suf fi cient to swing the output driver between fully OFF
and saturated (ON), respectively. It is NOT intended to indicate a range of linear operation.

Noise speci fi cation includes both digital and analog noise.
