Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values, except differential input voltage, are with respect to the network ground terminal.
2. Differential input voltage is measured at the noninverting input with respect to the corresponding inverting input.

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-resistor in series with each input.
4. The input not under test is grounded.
