SN74AHC14-EP: Need the VOL max information at -40°C to +85°C for SN74AHC14-EP and SN74AHC14Q-Q1

Part Number: SN74AHC14-EP
Other Parts Discussed in Thread: SN74AHC14Q-Q1, SN74AHC14

Hi, 

I'm trying to choose an alternative for one of the existing component in our designs. The existing component supports only -40°C to +85°C. I am considering SN74AHC14-EP or SN74AHC14Q-Q1 as an alternate. 

The datasheet for SN74AHC14 mentions the VOL max data for -40°C to +85°C as 0.44V and -40°C to +125°C as 0.5V.

But the datasheets for SN74AHC14-EP and SN74AHC14Q-Q1 mention the VOL max only for -40°C to +125°C. 

Since the SN74AHC14-EP and SN74AHC14Q-Q1 are enhanced products of SN74AHC14, do they have VOL max limited to 0.44V at -40°C to +85°C even though this temperature range specifically not mentioned in the datasheets? Could you please confirm?

Thank you, 

Komal Charan Garlapati.

    Hi Komal,

    Since the EP and Q1 parts are only tested from -40°C to +125°C, we can only guarantee the max VOL  in the datasheet for the range tested. Keep in mind these are the worst case values so the device will often output a lower voltage than the maximum VOL listed.
