The QS3VH244 HotSwitch is a high bandwidth, 8-bit bus switch. The QS3VH244 has very low ON resistance, resulting in under 250ps propagation delay through the switch. The switches can be turned ON under the control of the LVTTL-compatible xG signal for bidirectional data flow with no added delay or ground bounce. 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 impedence, and over-voltage tolerance makes the QS3VH244 ideal for high performance communications applications.
