Notes:
3.
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 direction.
4.
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.
5.
fMAXD generator input conditions: tr=tf < 1 ns (10% to 90%), 50% duty cycle, 0 V to 3 V. Output criteria: duty
cycle=45% / 55%, VOD > 250 mV, all channels switch.
6.
fMAXT generator input conditions: tr=tf < 1 ns (10% to 90%), 50% duty cycle, VID=200 mV, VCM=1.2 V. Output
criteria: duty cycle=45% / 55%, VOH > 2.7 V. VOL < 0.25 V, all channels switching.
