SN74HCS595: VIL and VIH

Part Number: SN74HCS595

Tool/software:

Hello,

If I am reading the datasheet correctly at VCC=2V it looks like to be sure a you have a high the signal needs to be at least 1.5V and to be sure you have a low the signal needs to be below .3V.

Is that correct?

Thanks,

John

So the Ibis model for this device shows that the VINL=.835V and VINH=1.1V with a VCC of 2.25V. So are those suppose to be typical values?

Hi John,

Yes these files use typical/nominal values.
