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 terminals. The bination of near-zero propagation delay, high OFF impedance, and over-voltage tolerance makes the QS3VH251 ideal for high performance minucation applications. The QS3VH251 is characterized for operation from -40°C to +85°C. The IDT logo is a registered trademark of Integrated Device Technology, Inc.
