The IDTQS3VH16244 HotSwitch is a 16-bit high band bus switch. The IDTQS3VH16244 has very low ON resistance, resulting in under 250ps propagationdelay through the switch. The switches can be turned ON under thecontrol of the LVTTL-compatible xG signal for bidirectional data flow with noadded delay or ground bounce. In the OFF and ON states, the switches are5V-tolerant. In the OFF state, the switches offer very high impedance at theterminals.

The combination of near-zero propagation delay, high OFF impedance, andover-voltage tolerance makes the QS3VH16244 ideal for high performancecommunications applications.

The IDTQS3VH16244 is characterized for operation from -40 to +85.
