Description

   The IDTQS3VH861 HotSwitch with 10-bit flow-through pin out is a high bandwidth bus switch.  The IDTQS3VH861 has very low ON resistance,
resulting in under 250ps propagation delay through the switch.  The switches are controlled by active low enable (BE) control.  In the ON state,the switches 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 impedance,and over-voltage tolerance makes the IDTQS3VH861 ideal for high perfor-mance communications applications.

   The IDTQS3VH861 is characterized for operation from -40 to +85.
