FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH251 HotSwitch Quad 2:1 multiplexer/demultiplexer is a high
bandwidth bus switch. The QS3VH251 has very low ON resistance, resulting
in under 250ps propagation delay through the switch. The Select (Sx) input
controls the data flow. The multiplexers/demultiplexers are enabled when the
Enable (
E
) input is low. In the ON state, the switches can pass signals up to 5V.
In the OFF state, the switches offer very high impedence at the termnals.
The combination of near-zero propagation delay, high OFF impedance, and
over-voltage tolerance makes the QS3VH251 ideal for high performance
commnucation applications.
The QS3VH251 is characterized for operation from-40
°
C to +85
°
C.
