FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The QS3VH862 HotSwitch with 10-bit active high and low enable is a high
bandwidth bus switch. The QS3VH862 has very low ON resistance,
resulting in under 250ps propagation delay through the switch. The
switches are controlled by independent active low enable (BE) and active
high enable (BE) controls. 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 QS3VH862 ideal for high perfor-
mance communications applications.
The QS3VH862 is characterized for operation from -40°C to +85°C.
