ELECTRICAL CHARACTERISTICS over operating temperature range, V
Typical Data is at T
Negative current is defi ned as coming out of (sourcing) the specifi ed terminal.
As used here, -100 is defi ned as greater than +10 (absolute magnitude convention) and the minimum is implicitly zero.
* Measurement includes output fault-sensing pull-down current.
