INDUSTRIAL TEMPERATURE RANGE
FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH16233 HotSwitch is a 32-bit to 16-bit high bandwidth bus
switch, which can multiplex or demultiplex data. The QS3VH16233 has
very low ON resistance, resulting in under 250ps propagation delay
through the switch. This device can be used as two 16-bit to 8-bit
multiplexers or as one 32-bit to 16-bit multiplexer. SELx inputs control the
data flow. TESTx inputs control either one or two ports connection. 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 also makes the QS3VH16233 ideal for high
performance communications applications.
The QS3VH16233 is characterized for operation from -40°C to +85°C.
