Note 4: All typical values are at T_A = 25°C and with V_CC = 3.3V.
Note 5: 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 6: 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 7: f_MAX criteria: Input t_R = t_F < 1ns, 0V to 3V, 50% Duty Cycle; Output V_OD > 250 mv, 45% to 55% Duty Cycle; all switching in phase channels.
Note 8: Test Circuits in Figures 2, 4, 6 are simplified representations of test fixture and DUT loading.
