INDUSTRIAL TEMPERATURE RANGE

DESCRIPTION:

The QS34XVH2245 is a high bandwidth, 32-bit bus switch. The

QS34XVH2245 with 25

Ω 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 individual LVTTL-compatible Output

Enable (OEx) signals 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 impedance at the

terminals.

The combination of small propagation delay, high OFF impedance,

and over-voltage tolerance makes the QS34XVH2245 ideal for high

performance communications applications.

The QS34XVH2245 is characterized for operation from -40

°C to

+85

°C.
