SN74LVC1G08: Is it capable of up-voltage translation?

Part Number: SN74LVC1G08

Hi, teams!

We use SN74LVC1G08 for voltage translation from 3.3V to 2.5V. (Vcc =2.5V, VOH=2.5V, VIH3.3V)

Is the SN74LVC1G08 capable of up-voltage translation?

For example, Is it able to translate from 2.5V to 3.3V? (Vcc=3.3V,VOH=3.3V, VIH=2.5)

According to the datasheet of SN74LVC1G08, VIH is over 2.0V(min) when I use 3.3V Vcc. 

Then, VOH can output up to Vcc(3.3V) also. 

It looks like the behavior of up-voltage translation but I couldn't find the sentences regarding this feature in this datasheet.
Therefore, I posted this question.

    Hi,

    Your reasoning is correct. Based on VIH(min) = 2.0V for the SN74LVC1G08 at Vcc = 3.3V, it should be able effectively up-translate from a 2.5V device to 3.3V assuming the VOH of the 2.5V device exceeds VIH(min) = 2.0V.

    I also recommend checking out the SN74AUP1T08 to see if it fits your application. It is designed for up-translation, including from 2.5V to 3.3V.
