Conditions: (Refer to test circuit.)
T_opr = 25°C, V_DD = V_IH = 3.3 V and 5 V, V_OUT = 0.7 V, V_IL = 0 V, R_EXT = 490 Ω,
V_L = 3.0 V, R_L = 60 Ω, C_L = 10.5 pF
Note 5: If the device is connected in a cascade and t_r/t_f for the waveform is large, it may not be possible to achieve
the timing required for data transfer. Please consider the timings carefully.
