The QS3VH384 has very low ON resistance, resulting in under 250ps propagation delay through the switch. Two banks of five switches are controlled by independent (xOE), LVTTL compatible signals for bidirectional data flow with no added delay or ground bounce. In the ON state, the switch 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 imp...
