Negative current is defi ned as conventional current coming out of (sourced from) the specifi ed device terminal.
Typical data is at T
In these tests, the vector X is intended to represent positive and negative fi elds suffi cient to swing the output driver between fully OFF
Noise specifi cation includes both digital and analog noise.
