Electrical Characteristics (continued)
(V_CC = +3.0V to +3.6V, C_CL = 75nF coupling capacitor on each output, R_L = 50I on each output, T_A = -40°C to +85°C, unless other-
wise noted. Typical values are at V_CC = +3.3V and T_A = +25°C.) (Note 3)

Note 3: All devices are 100% production tested at T_A = -40NC to +85NC. Specifications for all temperature limits are guaranteed by
design.
Note 4: Guaranteed by design.
Note 5: Rise and fall times are measured using 20% and 80% levels.
