Electrical Characteristics (Continued)

Note 4: For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating

conditions.

Note 5: Duration of the short circuit should not exceed one second.

Note 6: Standard deviation is a measure of the statistical distribution about the mean as derived from the formula:

Note 7: Temperature coefficient of timing capacitor and timing resistor are not taken into account.
