SN74LVC1G125: 5v supply, 3.3v input

Part Number: SN74LVC1G125
Other Parts Discussed in Thread: SN74LV1T125, SN74AHCT1G125

Hello,

We are considering using this part for our product, however the issue is that we are expecting to power this with a 5.15V source (USB), however the input is about 3.28V. From the data sheet, it mentions that for Vcc between 4.5-5.5V, VIH = 0.7*Vcc. However, our input is only about 0.63 of Vcc. So my question is, how rigid is the VIH threshold, and do we need to re-think our design?

Thank you,

-Ricardo
