DESCRIPTION:
bus switches in a flow-through pinout. The low ON resistance of the
QS32X245 allows inputs to be connected to outputs without adding propa-
gation delay and without generating additional ground bounce noise. The
Output Enable (OEn) signals turn the switches on similar to the OEn signal
of the 74'245.

... Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to L the system. Propagation delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. ...
