DC ELECTRICAL CHARACTERISTICS (continued)
(V_CCA = V_CCI = V_CCD = 5V, V_CCO = 3.3V, V_EE = -5V, GNDA = GNDI = GNDO = GNDD = GNDR = 0V, VOSADJ = SAMPADJ =
open, digital output pins differential R_L = 100Ω. Specifications ≥ +25°C guaranteed by production test, < +25°C guaranteed by
design and characterization. Typical values are at T_A = +25°C, unless otherwise noted.)
