Hello,
in the SN74LVC1G14 datasheet (Revision Y) there is a figure of interpolated threshold voltages:
While the traces of Vt+ min/max are ok, the traces of Vt- are strange:
Below Vcc=3V the trace values are as described in the Electrical Characteristics.
But above Vcc=3V, the trace values do not match the values in the Electrical Characteristics at all:
Wich values are correct?
