DESCRIPTION:
bus switches in a pinout compatible with 74FCT245, 74F245, 74ALS/AS/
LS245 8-bit transceivers. The low ON resistance of the QS3245 allows
inputs to be connected to outputs without adding propagation delay and
without generating additional ground bounce noise. The Output Enable
(OE) signal turns the switches on similar to the OE 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. ...
