(1) For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions.
(2) Timing-interval error is defined as the difference between the measured value and the average value of a random sample from each
process run.
(3) Values specified are for a device in a monostable circuit similar to Figure 2 , with the following component values: R
A
= 2 k Ω to 100 k Ω ,
C = 0.1 µ F.
(4) On products compliant to MIL-PRF-38535, this parameter is not production tested.
(5) Values specified are for a device in an astable circuit similar to Figure 1 , with the following component values: R
