The algebraic convention, in which the less positive (more negative) limit is designated as minimum, is used in this data sheet for threshold levels
only.
§Only one output should be shorted at a time, and duration of the short circuit should not exceed one second.
NOTES:
3. The expanded threshold parameter is tested with a 500-
resistor in series with each input.
4. The input not under test is grounded.
