Hi team,

What's the min negative voltage of the SN74LVCH162244AGR? (both the DC value and transient value-----for example 10ns)

Thanks.

-0.5V, as listed in the absolute maximum ratings table.

Hi,

whether we can use series resistor to control the input current to solve it？although the voltage is smaller than -0.5v(may be -1v). Thanks.

The ESD protection diodes will clamp the voltage; footnote (2) of the absolute maximum ratings allows this.
