Datasheet

NOTE :
1. For input only pins except /RESET : V
REF = VREFCA (DC).
2. See Overshoot and Undershoot Specifications section.
3. The AC peak noise on V
REF may not allow VREF to deviate from VREFCA (DC) by more than ±1% VDD
(for reference : approx. ±15 mV).
4. For reference : approx. VDD/2 ±15 mV.
5. VIH(dc) is used as a simplified symbol for VIH.CA(a) 1.35V : DC90, b) 1.5V : DC100)
6. VIL(dc) is used as a simplified symbol for VIL.CA(a) 1.35V : DC90, b) 1.5V : DC100)
7. VIH(ac) is used as a simplified symbol for VIH.CA(AC175) and VIH.CA(AC150); VIH.CA(AC175) value is used when
VREF + 175mV is referenced and VIH.CA(AC150) value is used when VREF + 150mV is referenced.
8. VIL(ac) is used as a simplified symbol for VIL.CA(AC175) and VIL.CA(AC150); VIL.CA(AC175) value is used when
VREF - 175mV is referenced and VIL.CA(AC150) value is used when VREF - 150mV is referenced.
