The QS3VH16212 Bus Exchange HotSwitch with 24-bits is a high bandwidth bus switch. The QS3VH16212 has very low ON resistance, resulting in under 250ps propagation delay through the switch. The device operates as a 24-bit bus switch or a 12-bit bus exchanger, which provides data exchanging between the four signal ports through the data-select (S0 - S2) terminals. In the OFF and ON states, the switches are 5V-tolerant. 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 QS3VH16212 ideal for high performance communications applications. The QS3VH16212 is characterized for operation from -40C to +85C.
