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.
