ELECTRICAL CHARACTERISTICS (continued)
(V_CC = +3.0V to +3.6V, C_CL = 200nF coupling capacitor on each output, R_L = 50I on each output, T_A = 0NC to +70NC, unless oth-
erwise noted. Typical values are at V_CC = +3.3V and T_A = +25NC.) (Note 3)

Note 3: All devices are 100% production tested at T_A = +70NC. Specifications over operating temperature range are guaranteed
by design.
Note 4: Guaranteed by design, unless otherwise noted.
Note 5: Equivalent to same amount of deemphasis driving the input.
Note 6: Rise and fall times are measured using 20% and 80% levels.
