1 ns propagation delay — bus timing margin
The 1 ns propagation delay from LE to Q (or D to Q when transparent) is specified. For typical automotive CAN or LIN interfaces, or industrial backplanes, this delay is within margin.
24 mA output drive and fan-out
Each output can sink or source 24 mA. When driving long backplane lines or high-capacitance loads, derate the number of parallel loads to stay within the package's total current limit.
