Note 3: All typical values are at TA = 25°C and with VCC = 5V.
Note 4: tSK(LH), tSK(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: tSK(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: fMAX Criteria: Input tR = tF < 1 ns, 0V to 3V, 50% Duty Cycle; Output VOD > 250 mV, 45% to 55% Duty Cycle; all output channels switching in phase.
Note 7: Test Circuits in Figure 2 and Figure 4 are simplified representations of test fixture and DUT loading.
