INDUSTRIAL TEMPERATURE RANGE
DESCRIPTION:
The QS32XVH2245 HotSwitch is a high bandwidth, 16-bit bus switch. The
QS32XVH2245, with 25Ω ON resistance and 1.35ns propagation delay, is
ideal for line matching and low noise environments. The switches can be turned
ON under the control of the LVTTL-compatible Output Enable (OEx) signal for
bidirectional data flow with no added delay or ground bounce. In the ON state,
the switches can pass signals up to 5V. In the OFF state, the switches offer very
high impedence at the terminals.
The combination of small propagation delay, high OFF impedance, and
over-voltage tolerance makes the QS32XVH2245 ideal for hot-swapping
applications.
The QS32XVH2245 is characterized for operation from -40°C to +85°C.

– No DC path to VCC or GND
– 5V tolerant in OFF and ON state
• 5V tolerant I/Os
• Flat RON characteristics over operating range
• Rail-to-rail switching 0 - 5V
• Bidirectional dataflow with near-zero delay: no added ground
bounce
• Excellent RON matching between channels
•V
CC operation: 2.3V to 3.6V
• High bandwidth
• LVTTL-compatible control Inputs
• Undershoot Clamp Diodes on all switch and control Inputs
• Low I/O capacitance, 4pF typical
