DESCRIPTION:

bandwidth bus switch. The QS3VH257 has very low ON resistance,

resulting in under 250ps propagation delay through the switch. The Select

(S) 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 terminals.

and over-voltage tolerance makes the QS3VH257 ideal for high perfor-

mance communication applications.

The QS3VH257 HotSwitch Quad 2:1 multiplexer/demultiplexer is a high

The combination of near-zero propagation delay, high OFF impedance,

The QS3VH257 is characterized for operation from -40°C to +85°C.
