NOTE 1. For input only pins except

REET. Vref = VrefCA(DC).

NOTE 2. See “Overshoot and Undershoot Specifications” .

NOTE 3. The ac peak noise on VRef may not allow VRef to deviate from VRefCA(DC) by more than +/-1% VDD (for reference: approx. +/- 15 mV).

NOTE 4. For reference: approx. VDD/2 +/- 15 mV.

NOTE 5. VIH(dc) is used as a simplified symbol for VIH.CA(DC100)

NOTE 6. VIL(dc) is used as a simplified symbol for VIL.CA(DC100)

NOTE 7. VIH(ac) is used as a simplified symbol for VIH.CA(AC175), VIH.CA(AC150), VIH.CA(AC135), and VIH.CA(AC125); VIH.CA(AC175)

value is used when Vref + 0.175V is referenced, VIH.CA(AC150) value is used when Vref + 0.150V is referenced, VIH.CA(AC135) value

is used when Vref + 0.135V is referenced, and VIH.CA(AC125) value is used when Vref + 0.125V is referenced.

NOTE 8. VIL(ac) is used as a simplified symbol for VIL.CA(AC175), VIL.CA(AC150), VIL.CA(AC135) and VIL.CA(AC125); VIL.CA(AC175) value

is used when Vref - 0.175V is referenced, VIL.CA(AC150) value is used when Vref - 0.150V is referenced, VIL.CA(AC135) value is used

when Vref - 0.135V is referenced, and VIL.CA(AC125) value is used when Vref - 0.125V is referenced.

NOTE 9. VrefCA(DC) is measured relative to VDD at the same point in time on the same device
