Hi,
Customer found the output will be high when one input is 2.65V with Vcc=5.0V. The value-VIH in datasheet is 3.85V @5.5Vcc. How to explain this issue?
Thanks a lot!

Hi Andy,
Please refer to this FAQ: [FAQ] How does a slow or floating input affect a CMOS device?
2.65V is in between the switching threshold, this is an unknown region of the device.
