The QS3VH16861 has very low ON resistance, resulting in under 250ps propagation delay through the switch. The switches are controlled by active low enable (BEx) controls. 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-voltag...
