SN74AHC14: Need the propagation delay information for -40°C to +85°C

Hi, 

I'm trying to choose an alternative for one of the existing component in our designs. I am considering SN74AHC14PW as an alternate. 

Although SN74AHC14PW supports -40°C to +125°C, my existing design uses a component which is rated at -40°C to +85°C. I have observed that the SN74AHC14 data sheet mentions the propagation delay for the -40°C to +125°C temp range and it is more than that of the other device, which is rated at -40°C to +85°C.

So, I would like to know if you have information about the propagation delay for the temperature range of -40°C to +85°C. If it matches with the existing component, I would like to proceed with this part as an alternate. 

Thank you, 

Komal Charan.
