† The algebraic convention, where the less positive (more negative) limit is designated as minimum, is used in this data sheet for threshold levels
only.
‡ All typical values are at VCC = 5 V, TA = 25°C.
§ 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-Ω resistor in series with each input.
4. The input not under test is grounded.
