Typical Data is at T_A= +25°C and V_CC= 5 V and is for design information only.

Negative current is deﬁned as coming out of (sourcing) the speciﬁed terminal.

As used here, -100 is deﬁned as greater than +10 (absolute magnitude convention) and the minimum is implicitly zero.

* Measurement includes output fault-sensing pull-down current.
