(1) Test conditions are C1–C4 = 0.1 µF at V_CC = 3.3 V ± 0.3 V; C1 = 0.047 µF, C2–C4 = 0.33 µF at V_CC = 5 V ± 0.5 V.
(2) All typical values are at V_CC = 3.3 V or V_CC = 5 V, and T_A = 25°C.

(2) All typical values are at V_CC = 3.3 V or V_CC = 5 V, and T_A = 25°C.
(3) Pulse skew is defined as |t_PLH – t_PHL| of each channel of the same device.
