FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH2245 is a high bandwidth 8-bit bus switch. The QS3VH2245,
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 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°C to +85°C.
