Renesas Electronics QS3VH251QG, Bus Switch

The Renesas Electronics hot switch quad 2:1 multiplexer/demultiplexer is a high bandwidth bus switch.It has very low ON resistance, resulting in under 250 ps 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 5 V. 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 this ideal for high performance comminucation applications. It is characterized for operation from -40°C to +85°C.
