CHARACTERISTICS
V_CCA = V₃ to V₄ = 4.75 to 5.25 V; V_CCD = V₁₁ to V₁₂ and V₂₈ to V₂₇ = 4.75 to 5.25 V; V_CCO = V₁₃ to V₁₄ = 3.0 to 5.25 V;
AGND and DGND shorted together; T_amb = 0 to +70 °C; typical values measured at V_CCA = V_CCD = 5 V and
V_CCO = 3.3 V; V_i(p-p) = 2.0 V; C_L = 15 pF and T_amb = 25 °C; unless otherwise specified.
