For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
Timing interval error is defined as the difference between the measured value and the average value of a random sample from each
process run.
Values specified are for a device in a monostable circuit similar to
with the following component values: R
A
= 2 kΩ to 100 kΩ,
C = 0.1
µF.
On products compliant to MIL-PRF-38535, this parameter is not production tested.
