The IDTQS3VH16212 Bus Exchange HotSwitch with 24-bits is a highbandwidth bus switch. The IDTQS3VH16212 has very low ON resistance,resulting in under 250ps propagation delay through the switch. The deviceoperates as a 24-bit bus switch or a 12-bit bus exchanger, which providesdata exchanging between the four signal ports through the data-select (S₀- S₂) terminals. In the OFF and ON states, the switches are 5V-tolerant. Inthe 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 IDTQS3VH16212 ideal for high performancecommunications applications.

The IDTQS3VH16212 is characterized for operation from -40 to +85.
