Notes:
1. For input only pins except RESET#. V REF = V REFCA(DC) .
2. See section 10.12 “ Overshoot and Undershoot Specifications ” on page 121.
3. The AC peak noise on V REF may not allow V REF to deviate from V REFCA(DC) by more than ± 1% V DD (for reference: approx.
± 15 mV).
4. For reference: approx. V DD /2 ± 15 mV.
5. V IH(DC) is used as a simplified symbol for V IH.CA(DC100) .
6. V IL(DC) is used as a simplified symbol for V IL.CA(DC100) .
7. VIH (AC) is used as a simplified symbol for V IH.CA(AC175) , V IH.CA(AC150) , V IH.CA(AC135) , and V IH.CA(AC125) ; V IH.CA(AC175)
value is used when V REF + 0.175V is referenced, V IH.CA(AC150) value is used when V REF + 0.150V is referenced,
V IH.CA(AC135) value is used when V REF + 0.135V is referenced, and V IH.CA(AC125) value is used when V REF + 0.125V is
referenced.
8. V IL(AC) is used as a simplified symbol for V IL.CA(AC175) , V IL.CA(AC150) , V IL.CA(AC135) and V IL.CA(AC125) ; V IL.CA(AC175)
value is used when V REF - 0.175V is referenced, V IL.CA(AC150) value is used when V REF - 0.150V is referenced,
V IL.CA(AC135) value is used when V REF - 0.135V is referenced, and V IL.CA(AC125) value is used when V REF - 0.125V is
referenced.
