FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH244 HotSwitch is a high bandwidth, 8-bit bus switch. The
QS3VH244 has very low ON resistance, resulting in under 250ps propagation
delay through the switch. The switches can be turned ON under the control
of the LVTTL-compatible xG 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 near-zero propagation delay, high OFF impedence, and
over-voltage tolerance makes the QS3VH244 ideal for high performance
communications applications.
The QS3VH244 is characterized for operation from -40°C to +85°C.
