Limits

Typical Data 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.

* All inputs simultaneously, all other tests are performed with each input tested separately.
