Functional operation under these conditions is not implied. Note 2: Either voltage limit or current limit is sufficient to protect inputs. Note 3: All outputs loaded; thresholds on input associated with output under test. Note 4: Maximum test duration 2.0 ms, one output loaded at a time. www.national.com 2 |
