Hi Experts,
Do you have a distribution data of VCTL? It is ok for a reference data.
Best Regards,
Fujiwara

Yasushi-san,
I do not have large sample distribution data. There are limits in the data sheet EC table , section 6.5. The population distribution will fall well inside the limits.
The VCTRL , control voltage, test shows limits that are +/-20% for 1.5V, and +/-15% for 5V, and +/-7.5% for 12V
The 'timing accuracy' test can also be used to indirectly know VCTL internally. It is +/-14% for 1.5V,and +/-9% for 5V, and +/-14% for 12V
The temperature shift (and voltage shift) are just typically values.
I do have data for 3 samples at 6 temperatures (all mixed together)
LMC555 VCTRL (ratio) vs. VDD supply voltage (-40C, -10C, 25C, 55C, 85C, 125C)
Yasushi-san,
The TLC555 is another device that is very similar and interchangeable in many applications.
I do not have large sample distribution data.
The 'timing accuracy' test (data sheet section 6.7) can also be used to indirectly know VCTL internally. It is +/-3% for supply of 5V to 15V
I do have data for 3 samples at 6 temperatures (all mixed together)
TLC555 VCTRL (ratio) vs. VDD supply voltage (-40C, -10C, 25C, 55C, 85C, 125C)
I used the same chart scale as the LMC555 data to make it easier to compare.
