TPS53689: SVID Data input logic low spec

How to define the spec for SVID Data input logic low ?

Is the input logic low less than 0.45V ? or have the other way to define spec ?

    Hi Nick,

    On SVID Data and Clock lines, if voltage is less than 0.45V with an hysteresis of 50mV is guaranteed as logic Low. For example if the voltage is 0.8V it corresponds to logic High and then if voltage drops to 0.2V(less than 0.45V) it changes to logic low and will continue to read the logic as low until the voltage is below 0.5V.

    Best Regards,

    Chanakya.
