CHARACTERISTICS
V_CCA = V11 (or V19, V27 or V99) referenced to AGND (V13, V21, V29 or V96 = 4.75 to 5.25 V; V_CCD = V95 referenced
to DGND (V86) = 4.75 to 5.25 V; V_DDD = V40 referenced to V_SSD (V41) = 4.75 to 5.25 V; V_CCO = V59
(or V69, V79 or V85) referenced to OGND (V48, V60, V70 or V82) = 4.75 to 5.25 V; AGND, DGND, OGND and V_SSD
short circuited together. T_amb = 0 to 70 °C; typical values measured at V_CCA = V_DDD = V_CCD = V_CCO = 5 V and
T_amb = 25 °C; unless otherwise specified.
