§
The algebraic convention, in which the less positive limit is designated minimum, is used in this data sheet for threshold voltage levels only.
NOTES: 3. Refer to ANSI Standard EIA/TIA-422-B and EIA/TIA-423-A for exact conditions.
4. Not more than one output should be shorted at a time, and the duration of the short circuit should not exceed one second.
