= +25°C and V
CC
= 5 V and is for design information only.
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.
