DESCRIPTION:

The QS3VH2245 is a high bandwidth 8-bit bus switch. The QS3VH2245,

with25

ΩONresistanceand1.35nspropagationdelay,isidealforlinematching

andlownoiseenvironments. TheswitchescanbeturnedONunderthecontrol

oftheLVTTL-compatibleOutputEnable signalforbidirectionaldataflowwith

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

theterminals.

The combination of small propagation delay, high OFF impedance, and

over-voltage tolerance makes the QS3VH2245 ideal for high performance

communicationapplications.

The QS3VH2245 is characterized for operation from -40

°C to +85°C.
