The QS3VH257PAG Electronic Components Hot Switch Quad 2:1 multiplexer/demultiplexer is a high bandwidth bus switch.The QS3VH257PAG is characterized for operation from -40°C to +85°C.
The QS3VH257PAG Electronic Components 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.
The combination of near-zero propagation delay, high OFF impedance, and over-voltage tolerance makes the QS3VH257PAG ideal for high performance communication applications.
