SN74LVC1G86: Application issues

Part Number: SN74LVC1G86

Hi Team,

Regarding product SN74LVC1G86DCKT, what is the input voltage considered high level when VCC is 2.5V?
The current measured voltage is 1.2V, but the specification is written as 1.7V

    The datasheet guarantees that input voltages of 1.7 V or higher work correctly. It does not guarantee what happens for voltages between VIL and VIH. If you want your circuit to work correctly for any chip at any temperature, you must use voltages of at least 1.7 V.
