SN74HC14-Q1: Temp and design effect to the VT value of SN74HC14-Q1

Jessica Wu74

Part Number: SN74HC14-Q1

Hi team,

Could you please kindly help to confirm how much would be VT value of SN74HC14-Q1 could be changed by different temperature(like when the working temp changed from 25℃ to 125℃， then how much would the VT(both VT+ and VT-) value changed)?

Would different design also have a effect to the VT value?

Thank you very much for your kindly support.

Best regards

Hi Jessica,

The datasheet specs show this.

Hi Dylan,

Thanks a lot for your kindly reply. I tried found the spec on datasheet, but i failed to found the temp vs VT, we can only get the VT under the condition of 25℃。Could you please kindly help me to finger it out where the datasheet shows these information? Thank you again for your kindly support.

Best regards

Jessica

Hi Jessica,

Our min and max specs cover the recommended operating temp range as it says in the datasheet. So the Min and max spec will cover the 125 C Vt and the 25 C typ should show you how much it can deviate. However our specs also account for process variations so its not all due to temp.
