LMC555: LMC555 Threshold level temperature varitions

Part Number: LMC555

Good day Colleagues,

I understand, the threshold highly dependand on external RC tolerances, but could you tell me how this circuit inside depends on temperature?

the datasheet says the paramiters at +25 degC. Could you tell me what to expect at +85 degC for threshold, trigger, discharge levels?

the formula says 0.693, but the customer is interested to understand variations.

Thank you, Mikhail
