DESCRIPTION:
The QS34XVH2245 is a high bandwidth, 32-bit bus switch. The
QS34XVH2245 with 25Ω 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.
