Note 4: t_SK(LH), t_SK(HL) is the skew between specified outputs of a single device when the outputs have identical loads and are switching in the same direc-
tion.
Note 5: t_SK(PP) is the magnitude of the difference in propagation delay times between any specified terminals of two devices switching in the same direction
(either LOW-to-HIGH or HIGH-to-LOW) when both devices operate with the same supply voltage, same temperature, and have identical test circuits.
Note 6: f_MAX Criteria: Input t_R = t_F < 1 ns, V_ID = 300 mV, (1.05V to 1.35V pp), 50% duty cycle; Output duty cycle 40% to 60%, V_OL < 0.5V, V_OH > 2.4V.
All channels switching in phase.
Note A: All input pulses have frequency = 10 MHz, t_R or t_F = 1 ns
Note B: C_L includes all probe and jig capacitances
