I am having some difficultly understanding the values described in this product sheet for the SN74AHCT14 Schmitt Trigger Inverter:
http://www.ti.com/lit/ds/symlink/sn74ahct14.pdf
Given a Vcc of 4.5V, I would like to know the following:
- What is the lowest input voltage that would cause the trigger output to switch from low to high output?
- What is the highest input voltage that would cause the trigger output to switch from high to low output?
And where can I find this in the product sheet?
