CD74HC30: VIH required for 2.4V

Part Number: CD74HC30

As per datasheet it says for VCC 1.9V, Vih requirement is 1.5V. So if we provide 2.4V, what is minimum requirement for this IC?

    Hi Jeevitha,

    We don't characterize VIH for 2.4 V supply so I don't have a value for you. However, the input threshold is typically around 1/2 VCC which can give you an idea. This threshold shifts over PVT so there is no guarantee that its the same from device to device.
