(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 T_A = 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.
