All parameters are guaranteed over the junction temperature range by design. Factory testing uses correlated test conditions to cover the specified

temperature and power supply voltage ranges.

[2]

Not tested in production; guaranteed by design.

[3]

Time-out occurs between the min and max values. Time-out is guaranteed not to occur below the min value; time-out is guaranteed to occur above the

max value.

[4]

Pulses shorter than the min value are guaranteed to be filtered out; pulses longer than the max value are guaranteed to be processed.
