DESCRIPTION:
QS3VH16211 has very low ON resistance, resulting in under 250ps
propagation delay through the switch. This device operates as a 24-bit bus
switch. When 1OE is low, 1An is connected to 1Bn. When 2OE is low, 2An
is connected to 2Bn. In the OFF and ON states, the switches are 5V-tolerant.
In the OFF state, the switches offer very high impedance at the terminals.
and over-voltage tolerance makes the QS3VH16211 ideal for high perfor-
mance communications applications. It is also suitable for switching wide
digital buses.
The QS3VH16211 HotSwitch is a 24-bit high bandwidth bus switch. The
The combination of near-zero propagation delay, high OFF impedance,
The QS3VH16211 is characterized for operation from -40°C to +85°C.

... Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the L 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. ...
