UNIT
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.
Values specified are for a device in an astable circuit similar to
with the following component values: R
A
= 1 kΩ to 100 kΩ,
C = 0.1
µF.
