The QS34XVH245 has very low ON resistance, resulting in under 250ps propagation delay through the switch. The switches can be turned ON under the control of individual LVTTL-compatible Output Enable (OEx) signals for bidirectional data flow with no added delay or ground bounce. In the ON state, the switches can pass 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-voltage tolerance makes the QS34XVH245 ideal for high performance communications applications. The QS34XVH245 is characterized fo...
