Hi Team,

Hi Jayden,
Pin 8 supplies power to the core circuitry, while pin 23 supplies power to the input buffer. If the voltage drop on pin 23 is only 0.15V, then you have nothing to worry about - it falls well into the spec for VIH - which requires that the input be 1.6V or greater. The voltage difference is acceptable.
Thanks,
Michael
