† All typical values are at VCC = 5 V, TA = 25°C.

‡ 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-

Ω resistor in series with each input.

4. ri is defined by ∆VI/∆II.

5. The input not under test is grounded.
