I am working on designing a circuit using an lm339 and an analog temperature sensor to activate a fan on either high or low speed, I have pretty much all of the details worked out to my satisfaction based on circuits I have found on here and other places on the internet, but when I started putting together my parts list to make an order I noticed that the LM339 is only rated from 0-70*C. Since this device will be installed in a car it will frequently be exposed to temperatures below this, and maybe above this as well (although it will be located in the cabin so it won't get as hot). Searching around I see the datasheet for the 139/239/339 indicates the LM239 will meet the temperature range requirements I have but I can't find any difference in the specifications between the LM239 and LM339 except the temperature range. Is there any other difference between the 2 parts except for this?
Thanks in advance for any help!
