(1)
For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
(2)
All typical values, except for parameter changes with temperature, are at TA = 25°C.
(3)
Duration of the short circuit should not exceed one second.
(4)
Standard deviation is a measure of the statistical distribution about the mean, as derived from the formula:
(5)
Temperature coefficient of timing capacitor and timing resistor is not taken into account.
