FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH16211 HotSwitch is a 24-bit high bandwidth bus switch. The
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.
The combination of near-zero propagation delay, high OFF impedance,
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 is characterized for operation from -40°C to +85°C.
