DESCRIPTION:
devices and provides a set of 32 high-speed CMOS compatible bus switches
in a flow-through pinout. This device is available in the MilliPaQ package,
the world's first small outline 32-bit solution. The low ON-resistance of the
QS34X245 allows inputs to be connected to outputs without adding propa-
gation delay and without generating additional ground bounce noise. When
Output Enable (OEn) is low, the switches are turned on, connecting bus A
to bus B. When OEn is high, the switches are turned off. This device is ideally
suited for 32/64 bit applications where board space is at a premium.

... 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. ...
