The QS3VH253 has very low ON resistance, resulting in under 250ps propagation delay through the switch. The Select (Sx) inputs control the data flow. The multiplexers/demultiplexers are enabled when the Enable (EA, EB) inputs are low. In the ON state, the switches can pass signals up to 5V. In the OFF state, the switches offer very high impedance at the terminals. The combination of near-zero propagation delay, high OFF impedance, and over-voltage tolerance makes the QS3VH253 ideal for high performance communication applications. The QS3VH253 is characterized for operation from -40°C to +85°C. YA YB The IDT logo is a registered trademark of Integrated Device Technology, Inc.
