FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH861 HotSwitch with 10-bit flow-through pin out is a high
bandwidth bus switch. The QS3VH861 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 imped-
ance, and over-voltage tolerance makes the QS3VH861 ideal for high
performance communications applications.
The QS3VH861 is characterized for operation from -40°C to +85°C.
