DESCRIPTION:
The QS3VH2245 is a high bandwidth 8-bit bus switch. The QS3VH2245,
with 25鈩?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 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 QS3VH2245 ideal for high performance
communication applications.
The QS3VH2245 is characterized for operation from -40擄C to +85擄C.
